Origami-class machines to run XP and do e-mail and Web-surfing
“…sources have provided a pretty clear picture of the mini-tablet devices. They will carry Microsoft’s software, but be made by several other companies, sources have said. They will also be larger than a typical handheld computer, with at least some of the devices using a roughly 7-inch screen.” - CNET.
Plus, they’ll run XP and be capable of “playing music and movies, editing documents, viewing e-mail and surfing the Internet.” And of doing justice to a variety of e-book readers–both the human and software varieties?

I work on the Microsoft team responsible for Origami as a product designer. Do you have any feedback on the device shown from an e-book perspective?
March 3rd, 2006 at 7:00 am
[...] Microsoft wants feedback on Origami for e-book reading! Seems that Microsoft in interested in Origami as an e-book platform. Paul Hoover wrote the following comment on Mar 3…"I work on the Microsoft team responsible for Origami as a product designer. Do you have any feedback on the device shown from an e-book perspective?" TeleRead has the comment which was also referred to from here. How about it… anyone here have any ideas for him on what would make an Origami device a good or bad e-book reader? BTW, if I followed my Google links properly, it seems that Paul is also a writer, so his interest in the subject is probably quite genuine and deep, not "just" another work project.

Most certainly I have feedback. The basics are very easy though and anyone can think of them. Implementing them might be harder. Simply said, we all read books for enjoyment and comfort. Everything that makes it harder or more annoying to read a book is bad. That is the driving thought you should keep in mind for any product you make.
This can translate to a variety of needs. Provide reading software which is easily customized in color, font, size and spacing. There are many popular readers around which you might look at.
Make it easy for people to put content on it. Either through a shop system or some -open- format. This includes a method to easily get said book onto the device. After all, if I need to spend more then a few moments to get a book on the device, or it involves annoying steps, it won’t be a pleasant reading experience.

Having used the Clie Th55, Plam LifeDrive, Nokia 9500 and HTC Universal as eBook readers I would say the key features you need are long battery life and a high resolution screen. I would also say the eBook reader has to be bug free, which is not my experience of using the MS Reader on the Universal.
March 3rd, 2006 at 8:33 am
Paul, to add to what Jaapjan said: if you have a preferred format, make sure that there is Free Software to convert to it, and give it to Matthew McClintock at Manybooks.net. He converts Project Gutenberg ebooks (and more) to a plethora of formats–as long as he can do the conversion automatically on his GNU/Linux box. (I cannot speak for Matthew of course; but he seems interested to convert to any format that makes sense, as long as he can.)
Also, getting these devices into the hands of users that will actually use them to read ebooks will give you far better feedback than what you could sollicit from people who can only see a picture of the device.
I myself would be interested in taking a peek at the the Origami, and report about it here on Teleread. (Contact info in the top menu, “Contact info and FAQs on TeleRead, blog, e-books, etc.”.)
March 3rd, 2006 at 9:05 am
Here are some thoughts from me as someone who uses etexts regularly as a scholar and is on the core team for two PalmOS-based etext-type projects (Plucker and PalmBible+). I do probably more than half of my book reading on my PDAs.
1. Usability outdoors is important. One can take books outside. It’s important to be able to take ebooks outside if they’re going to be like books.
2. For me, fast (and ideally somewhat sophisticated–at least distinguishing multiple-word and phrase searches) search capabilities are essential. They are, after all, one of the few things that ebooks can do that paper books can’t.
3. The ability to convert one’s own content, ideally from HTML and preserving linking, is essential. A lot of the best ebook material is public domain, because some of the best literature is in the public domain.
4. Nice fonts, adjustable-speed autoscrolling, color adjustments (at least one would like to be able to have a black on white mode for normal reading and a green/white on black mode for night reading) etc. are all good to have.
5. Button ergonomics matters. If one’s going to be lying on one’s back holding the ebook device above one in one hand, or sitting up in a bus holding the device in hand, the device should be designed so that it would be possible to press the buttons, at least ones for paging, comfortably with th same hand as the one that is holding the device. Moreover, this should work in landscape and portrait. There may also be handedness issues. My Sony Clie NX70’s left-side mounted jog-dial is close to ideal (though a bit too sensitive)–I can comfortably hold the device with one hand and spin the dial with my index finger. I’m right-handed, but I think it would work for a left-handed user about as well by using the thumb. Works fine in landscape, too. My Palm TX’s buttons are poorly placed for ebook use. There is no comfortable way of pressing the paging buttons that are under the screen while reading in portrait mode. Landscape is somewhat better, but pressing the buttons unbalances the stability of one’s grip. (I’ve remedied that by putting eGrip material (egrips.com) on my TX.)
The device in the picture seems to have OK button placement for right-handed landscape use–one can press the buttons with one’s thumb–though it depends a bit on weight, balance and how grippy the back is. For portrait use, it doesn’t seem so good, though one might be able to hold the device in one’s hand, if the hand is large, and try to curl one’s fingers around the top to press the buttons there. Failing that, two-handed use is what one is stuck with. A jog-dial on the side would really help.
On a related point, it’s distracting to have to pull out a stylus while reading (not least because it requires two hands). A button-only interface to the essentials (brightness, paging, hyperlink selection, probably book selection) is very useful.
6. Annotation abilities. An ebook should be able to do everything a book can do and more. Books (at least ones that one owns, not library ones) allow for annotating, underlining, etc. Ebooks should do the same.
7. Drag-scrolling is very nice in that eyes do not jump around the page much as in full-page scrolling. Both the page paradigm of MS Reader and the web-page paradigms for scrolling should be supported.

Well, as Paul must have known even before he posted his query, this site teems with well-informed e-book users. Now maybe he can help by further clarifying the kind of information he’s after. I focused on hardware basics, but it’s clear this discussion has evolved into one on software as well. Are we, then, indeed talking about an XP machine, as some press reports have suggested? That would considerably broaden the range of topics for discussion. Thanks. David
March 3rd, 2006 at 1:13 pm
I am interested in information regarding both hardware and software. I am an avid e-book reader on my treo and know from my own experience the problems and strengths of reading electronically. On my treo I switch between using my d-pad and the touch screen to page-turn. Any thoughts on pen/stylus/touch interaction? Also, any thoughts on panning like in a PDF vs page turns?
Another area of interest is where to get e-books. Free or public? I’ve searched for a lot of books that I’d really like to read to no avail. Are there resources out there unknown to me where users could potentially pick up most any book they want for free or for a small fee?
Yet another area of interest for me is education. Alexandar, what is your workflow for getting your scholarly texts on your pda. Do you reformat HTML? Are textbooks already in e-book format? Do you purchase texts from publishers? Do you annotate your text? Do you use e-books in the classroom (if you are a teacher).
And yes, puting these problems in front of users using the hardware and software is a great way to get feedback, but so is getting the opinions of subject matter experts.
Thanks a lot,
Paul
March 3rd, 2006 at 1:44 pm
I have never read an e-book due to the size of the screen on my Palm M105 then my Zire. I no longer use a PDA. But this would be the prefect device for me, and I am sure the high quality bigger screen would be great for reading books. Long battery life, lightweight and not be interupted by other sounds and messages and apps stealing focus while reading unless I selected to play music too.
March 3rd, 2006 at 2:48 pm

Selling a lot of devices might persuade the commercial book publishers to release more of their backlist at lower prices, or at least make them available to libraries with no restrictions on how many copies may be lent at one time.
With the majority of their titles, they won’t be risking a lot of money, and they would be increasing the readership of their authors.
Of course, that’s all indirect from your efforts.
But many people read websites offline, using a program like Plucker or Sunrise to create an e-book file automatically from new content on their watched websites. There’s no Plucker-compatible e-reader that runs under Windows — if MS Reader could accept Plucker pdb files, that would provide literally worlds of content.
March 3rd, 2006 at 3:18 pm
First of all, thanks Paul for your interest in getting input. (And a courageous move considering all the “demands” and frustrations we have as e-book fans who haven’t yet found the ideal device!)
There is a feature that I want to highlight because I believe it becomes much more important with Origami-like devices… access to my book and bookmarks on multiple devices (PC, Origami, pda/smartphone). That could mean wireless access to it, but because I’m not always “connected”, it really means synchronization of bookmarks on several devices and the ability to put the book itself on multiple devices.
There will, I would guess, be a lot of synching with these devices because it is not going to be the only device a user computes from. He/she will at different times be using a PC or Origami or PDA/Smartphone. If you are reading an ebook and have multiple devices, you really don’t want to have to go find a particular device to continue reading your novel, or have to do a text search to try to figure out where you left of last time. I read all ebooks on my Treo 650 for that very reason. The screen is small, but it’s adequate. And more importantly, not only is the book always available, but I can always continue at my present location without any hunting for the right page.
Also, I’d say that it’s very important to me to have a good selection of fonts and styles and sizes, and the ability to bring in additional quality fonts that are favorites.
The ability to bring in my own ebooks easily is definitely a critical factor for me in choosing an ebook reader. For example, I currently use eReader most of the time. I like the way I’ve been able to convert any MS Word document using a nifty macro and the eReader conversion software. Because MS Word can read a lot of formats, it gives me a lot of flexibility.
Multiplatform reader software support is a big help. That’s also one of the reasons I use eReader… it supports both PalmOS and Windows Mobile. I don’t want my content to be “stuck” if I decide to switch my OS.
One more comment. Well, pretty much a complaint about the MS Reader activation scheme. (Sorry! I know it’s probably not your fault.) It’s device based, and very limited in activations, yet activations are fragile - i.e. reloading the OS or hard resets, etc cause you to lose an activation. I really like MS Reader for reading. I love the textured backgrounds!!! But unless using “DRM workarounds”, I’d never buy a .lit file with MS Reader DRM. It’s too easy to do something that requires reactivation, and I’ve heard you can only activate 3 devices, including reactivations. Even the threat of losing the ebook due to that kind of event is reason to avoid it. Unless you’ve saved PPC activation files, or restore from a good backup, a few crashes of your pda and you’re done. Not to mention horror stories about no response when trying to extend to another activation with MS support. I could go on and on, but I’m sure you know what I mean, and I’m sure there are some great minds working on improvements. But as it stands, I just wouldn’t want any MS Reader DRM’d files. I want to feel some sense of stability if I buy a book. And if customers are not willing to buy a book in a particular format, that can really crimp sales and adoption of the associated ebook reader, no matter how great the reader hardware and software is.
I should also say that one handed operation and multiple ways to turn pages is a big deal because you hold a device for a long time when reading a book. I like low backlight levels for reading in bed. And I like to be able to see a clock and battery levels without having to choose a menu item or click on something.
A rocker switch (the D-pad on my Treo) is my favorite way to turn pages. I like the tactile feedback. But the D-pad on my Treo seems a bit small and the “click” is not satisfying. Especially with the skin case on it. The Sony Clie I had before it was great, but after the thousands of page turns, I basically wore out the page up/down switch and I’m afraid I’ll do the same to my Treo.
As has been mentioned before, outdoor readability is very important, as well as glare control. But also an unscratched screen is important to enjoy the reading experience. Screen protectors are fine, but it’s hard to find a durable and clear one that both protects well and is inexpensive.
A related issue is whether or not I feel like the device is “easy to drop.” Some things just seem to drop easy, and other things are easy to hold onto. I’d be afraid of a form factor and texture that is very droppable, unless there was a great case for it. Same thing about “breakable.” If it seems very fragile, and one drop will doom it with certainty, I’d be afraid to spend much on it. In fact, that’s one of my primary concerns about the upcoming Origami devices.
But I’m quite excited about Origami, and similar future devices. I wish you well with it, and as the technology improves I think this sort of mobile device (as if I really know exactly what it will be!) is going to become a greater and greater hit.
Hope there’s something here that is of interest or gives you some ideas. We’re probably going to do a lot of complaining no matter what you roll out, but we’re really cheering for you as we are for all groups that are forwarding the book reader and mobile computing device markets!

If this device indeed runs the full version of Windows XP, I imagine that this could be the first truly multi-format ebook device. Think of the possibilities of title choices between Mobipocket, eReader, Microsoft Reader, Adobe - that are available today on various online ebook stores!!
Add to that the ability to read outside, which the video (seen all over the web this week),certainly seems to indicate, plus the “book-size” screen, and voila! the Origami UMPC becomes the ultimate eBook reading device ever manufactured.
March 3rd, 2006 at 4:14 pm
The most important thing to me would be the ability to highlight and save highlighted portions of text to a seperate file.
March 3rd, 2006 at 4:51 pm
Off topic, but unlike PCs, personal devices should not crash and need constant rebooting. The software has to be simple and stable not complex and feature rich if it is buggy. I really hope M$ try to understand what the difference is between a personal device and a general purpose PC, which is used by many people in a typical household/company/etc.
March 3rd, 2006 at 5:09 pm
First a little background, to better understand my thoughts: I’m a novelist who has been publishing eBooks for seven years now on the web, and reading them for almost 25 years, all the way from my old TRS-80 now to my Treo, and just about every device in between. I would consider myself on the “expert” level now, as far as how to make documents in .pdb, .pml, .lit, .pdf and interactive .pdf. In 1999 I won a grant from the Illinois Arts Council for electronic publishing; I have published maybe 50 titles now in those years, both my own work and others. I am also the founder of a group called the Chicago Center for Literature and Photography, opening this September, who will be commercially publishing 20 eBooks a year, among other things.
First, I would please encourage Microsoft to create software for the Origami that accepted as many of the above-mentioned formats as possible, not just .lit (for MSReader), and to also add .txt, .flv (Flash), .html and .xml (RSS) (and of course OpenReader…but that goes without saying). There’s a real opportunity here that so far no eBook manufacturers have taken - to combine book reading, magazine reading, website reading and RSS feed reading, all into one simple application. This would be an amazing thing, I think - to have one device and one window, where I could tab from the latest Murakami novel to the New York Times, right to my friend’s blog. This will only happen, though, by embracing as many standards as possible, which so far no one has done.
Second, please give us all the great simple benefits that come with reading a paper book: easy and automatic bookmarking of where we left off, when clicking out of a document; the ability to write notes in the margins, and to highlight phrases; the ability to easily turn from “page” to “page” (versus one endless scrolling document). Since you asked, I myself would primarily want to highlight and take notes with a stylus, then turn pages with large friendly buttons, either real or virtual. I have found real resistance among many of my readers to embrace eBooks, mostly for this reason; that to this date, it’s still not as convenient as a paper book or magazine is. Apple closed this gap in music, for example, by creating the combination of iTunes and the iPod; I would love to see the Origami be the first device ever to close this gap with eBooks.
Third, like many others have said here, definitely a way for users to create their own documents. MSReader has a good history of this, though (of making it easy to convert many documents to .lit format, that is), so I imagine you will do the same with the Origami.
Fourth, and I know it’s a little too late for this, but I think the time has finally come where “electronic ink” systems can be taken seriously. This is the number-one reason I hear from my readers, as to why they don’t read eBooks; that no matter how fine the screen, they still simply can’t read it for longer than 30 or 45 minutes in a row, without their eyeballs going crazy. Nothing is ever going to get better with eBooks until this technology is finally improved.
I’ve enjoyed all the different prototypes and videos I’ve now seen of the possible finished product; I wouldn’t really change anything so far viewed, although that may change once I get to interact with the actual device.
Where to get eBooks: That’s another big problem, caused in this case by so many publishing companies not understanding the real strength of eBooks, and implementing them in very wrong ways. But that has nothing to do with Microsoft, and could be another 1,000 words on its own if I get started, so I won’t. In a nutshell - we need a YouTube for electronic books, but a lot of publishers are very threatened by this idea.
That’s it; I’ll make way now for others. Thanks for listening!

Paul, how very cluetrainesque of you to conduct your research in this way.
I’m not into gadgets much but this one has me all excited. I’ve been blogging about it for three days http://learnandteachonline.com/node/346
Ditto to a lot of what’s been said. One thing you might want to take into account that I haven’t seen mentioned is business use of devices for leisurely offline reading. So often if something like a work-related article is quite long you’d like to be able to curl up with it, like you would with a book or magazine. Lots of general business information , as well as vertical business info is available in PDF, and I have a feeling that’s going to be the main file format for business use, so Acrobat Reader would have to work perfectly.
I also work in publishing (for the National Safety Council, where we put out some 20 newsletters, three magazines and 100 books). As a practical matter a vertical publisher very often will not want to take the trouble to reformat the print version of a publication for electronic consumption. So, I’m thinking about page size for a large textbook-sized book or a magazine. It’s probably going to have to be displayed in landscape mode, but it would be really nice to plan how it fits into the shape of your device’s screen, and try to strike the right balance between font size and getting a page on no more than two screens full of text.
Also, for education purposes, you might want to consider some sort of LMS quiz plug-in that can be completed offline then submitted later online.

[...] Paul Hoover, apparently from the Origami team, is asking for feedback on the Origami concept with an eye towards ebooks. The dialogue so far is in TeleRead’s comment section! [...]
March 4th, 2006 at 8:34 am
[...] From information coming out at Teleread, it seems an e-book reader is also being planned. Microsoft has a fabulous e-reader (Microsoft Reader) in place, with DRM that enables it to deal with commercial, encrypted book titles. They also have long-standing arrangements with major publishers and the online booksellers. Sony’s Reader might be cheaper, but the Origami/UMPC will run XP, and will include WiFi access, not to mention color (both absent in Sony’s device). [...]
March 4th, 2006 at 12:58 pm
Just a few points:
1. Long batt life (8+ hrs of *real* usage, such as full backlight, wifi etc)
2. Indoor/Outdoor viewing display (whether you use transflective or what not, consumers don’t care a hoot, just make sure it can be seen, I don’t care if its called ABZ912 or RealDisplay)
3. Support for multiple DRM format *AND* open formats like HTML and text etc.
4. SD card support. Its cheap, reliable. period
5. Wifi (at least support 802.11b)
OPTIONAL:
1. Listen to mp3, audio books
2. Watch Video (very optional. Personally I don’t need it)
March 5th, 2006 at 6:25 pm
Myself, I think I’ll hold out for the day I find something that works with Thout/Open Reader, seeing as that’s the format I’m using to convert all my scholarly books. Being able to sync private (and downloaded public/group, if there’s no wireless card) notes with my other machines would also be nice.
March 6th, 2006 at 9:14 am
Weight and comfort of the physical unit come into play in a big way. If this is just a shrunk down laptop/clamshell design then it will be uncomfortable to use for reading when laying on the couch. For instance, I can hold and operate both a p-book and a eBookwise 1150 with one hand for reading, will I be able to do that with this?
Also how well the controls work with my favorite ebook reading software matters (ie. I don’t want to hunt for a keyboard arrow key to turn a page.)
March 7th, 2006 at 3:29 am
I came in late, so maybe this is a repeat. One-handedness thing is the first feature I look for besides screen-size. I loved my old HP because I could just flick the side rocker button. I also like to read anywhere, including outdoors. I detest DRM and have found that Palm’s is the easiest to work with: can read your book on as many devices as you like and unlock it with the credit card number. Palm had the best site going until I bought a Nokia 7710 under the impression it would read pdb’s. Sigh. Wi-fi is important; fiddling with cables is annoying. Outlining, highlighting, lookup. Search should start from current page and lap the book.
March 7th, 2006 at 2:51 pm
Does it have a microphone? I want an ebook I can prop up at the breakfast table and read with my hands full. That requires an audio prompt (a click of the tongue, perhaps?) to turn a page.
March 7th, 2006 at 3:40 pm
Great discussion and of course BIG kudos to Paul for asking for input! Have just a few things to add -
1) Please, please work with Libraries (and schools!) right from the get-go so that e-books for this reader can easily be acessible to everybody, not just the rich. I personally know that libraries are part of Microsoft’s vision - and they are a crucial piece of the solution to get e-books into the mainstream.
2) Unicode - make the device totally unicode compliant so that no matter what language (even non-roman alphabet ones!), any book can easily be read without being a technical genius.
3) Include a nice, smooth autoscroller! I use mine all the time and is one of the main reasons I use Mobi-Pocket instead of Microsoft Reader. One use is hands-free reading during lunch!
March 8th, 2006 at 5:52 pm
Just a few hardware-only comments:
1. The ability to rotate the screen through 180 degrees in 90 degree increments is important (or 360 degrees if buttons exist on only one side of the device). Button association should rotate with the screen (so top is always top, and left is always left, etc.)
2. Sometimes I read in the bathtub by placing my PDA in a Ziploc bag. All buttons should be manipulable while inside a bag.
3. I frequently read in bed in a darkened room. Even at its lowest setting my iPaq generates enough light to trouble my wife’s sleep, and can even be used as a flashlight. It is as important for the screen to be capable of being reduced to a *very* faint glow as it is for the screen to be readable in full sunlight.
4. Even with high-capacity batteries and low-power mode there will be times when you just can’t get to a wall socket. The device should accept standard AA or AAA alkaline batteries. If I were designing the device I would design it to use standard AA or AAA batteries, or their NiMH or Li counterparts, as its primary power source.
5. A standard USB port with drivers to accept keyboards, mice, USB wireless adapters, and GPS receivers is highly desirable. Indeed, the lack of wireless capability would not be a show stopper for me if I knew that they could be added through a standard USB port. The USB port could be used for synchronization with a PC, and could probably even be used as a battery charger.
March 11th, 2006 at 10:46 pm
Long time ebook reader. I use Ubook almost exclusively on a Dell Axim X5, to read 3 to 4 books a week. Ability to read lots of formats besides just a main ebook. Love that Ubook can read from a zipped file, which makes my preferred format zipped .html work as all the files are contained in one zip file. Universal file format reading is key. Simple interface with lots of control options to let the reader pick what works for them.
Instant on is a key element. Would really like to see ebook reading, mp3 and movie playing all bypass the operating system.
Easy adjust of brightness.
Like the idea of tabbed viewing of books, magazines, rss feeds - that was a superb idea.
Take advantage of the tablet interface and create gestures for book navigation as well (like in the Maxthon program, highly useful, so much so that I try to use gestures in other programs)
March 21st, 2006 at 1:21 pm
For me it should have a screen between 5 and 6 inches. Bigger than the PDA’s but smaller than tablets. Size around the typical Paperback. If it is to large for one hand it will not be carried enough to make it worthwhile.
Good readability inside & outside for those of us that no longer have 20 year old eyes.
Battery life must last through one days typical reading, ability to use microdrives and sd cards a big plus as would be USB host capability.
June 21st, 2006 at 5:53 pm
I have read eBooks primarily on three devices: The Nokia 3650, Sony Clie SJ22 (and, briefly, before the screen broke, the SJ20), and my new HTC Universal device. In all cases I’ve used the Mobipocket software, because for devices it just seems to work much better than the various alternatives. I’ve also read ebooks on my old-ish laptop, using MS eBook reader (because on PCs, that one’s better), but that’s just too large for regular use.
Controlling the ebook was easiest on the Clie by a long shot, in either hand, due to the absolutely brilliant jog-dial. The Universal has a rocker switch, but trying to use it for pageturning usually involves overshooting your page by miles because it takes too much force to use and repeats too quickly — but even with that fixed it would not be a match for the jog dial.
The screen is clearly best on the Universal — something with *at least* that pixel density would be good. To be useful for webbrowsing as well, I think 1024-wide would be better than 800-wide. The screen on the Clie wasn’t bad, but the fonts available let it down a bit. The screen on the 3650 was small, but it’s relatively high-dpi and so it’s nearly as good to read on as the SJ22 is. I’ll take high-dpi over sheer size any day (especially if the rest of the device shrinks with it).
Formatwise: I’m for convertible tablet, in whichever size. The problem there is that the typical hinge is weak. I think it might be good to explore a form factor where converting to tablet involves flipping the screen all the way back (flipping the base keyboard down, rather than having it in the middle). This is, of course, not really something that is within Microsoft’s purview, but a manufacturer might read this as well.
In re: battery life, it’d have to be PDA-like, rather than notebook-like, although my latest PDA is a bit of a batteryhog itself. For extended use (during, say, holidays) I’d like the ability to charge the battery by connecting whatever voltage I’ve got on the charge connector (at the very least 5V-6V) — one thing that came in really handy was a 4xAA battery holder with a charge cable attached. Even in darkest Transsylvania (literally), you can always get AA batteries, and you can usually find an internet cafe where you can plug your USB-charge cable in while you surf.
Connectivity out the wazoo — at least Bluetooth (and maybe IR) and WiFi, but preferably with an integrated UMTS(/HSDPA)/GPRS(/EDGE) radio in. Actual phone capability is more or less optional (perhaps just with BT headset). Hell, if you can fit in a GPS receiver while we’re at it, go for it (but the phone and especailly GPS functions, like in current PDAs, are probably best left more or less to the individual hardware manufacturer). But include a program to easily activate and deactivate all of that, for powersaving reasons.
I would not be averse to a version of the tablet that uses Flash rather than or in addition to a spinning hard drive (8GB CF is fairly affordable these days — Incidentally, SD and size permitting CF readers are a capital idea) — although I suspect you’d need to up the ram a bit and modify the OS to make properly sure you don’t trash the flash cells unnecessarily. Perhaps OS off Flash with a small scratch RAM disk for those bits that just work better with a ‘disk’ and a larger 1.8″ ipod-style hard drive that only activates when you’re doing things that need it. I suspect that this is beyond what Windows XP can do without major rewriting that’s no longer an option with Vista on the horizon.
A lot of this is probably not yet an option wth the current state of the art, price/performance wise, but I suspect that a device such as I describe could be made at a reasonable price (say, the ~1k that the Universal costs now) within two or three years.
