I like it in some ways, but it's the wrong compromise! I want the best of both worlds (power and portability) not the worst! This is less powerful/usable than a convertible tablet/notebook, with a much smaller screen, yet lacks the portability of a PDA. May as well carry a subnotebook (only slightly larger and equally pocketable--meaning NOT) and be able to type and use keyboard shortcuts.
Plus battery life on these seems to be poor--when they really need BETTER life than a laptop. A laptop is often used near an outlet anyway. But something ultraportable and able to be used while standing begs to be used anywhere, anytime. Preferrably without having to think about charging every 3 hours.
I personally DO want a semi-pocketable, fully-capable computer, despite the screen/input sacrifices that would be entailed. (Whether that means handwriting-recognition or just a very tiny keyboard--a super-subnotebook sounds fine to me.)
My reason is, I can't always PREDICT when I'll need/want my PowerBook. To show some photos, play a game, email a contract, or make emergency changes on a client's web site. So I end up a lot of the time not having my Mac with me when I need/want it. Conversely, I often end up lugging the thing around and not using it! Either way, I lose.
I avoided the same dilemma with a digital camera--I knew if I got a big one I wouldn't have it with me when I wanted to take a picture. So I got a really tiny one with full-size features (Pentax Optio S). I want the same option in a computer. I want it small enough that I always (or nearly) have it with me, without it being a burden. And I want it capable enough to do just about anything--maybe not well (that would demand more speed, bigger screen, full keyboard, etc.)--but it can DO what I need. That's so much better than nothing!
And if I can connect any old display and keyboard to it, I'd magically have a full-size Mac at most places I visit anyway. Not THAT's the best of both worlds.
These Origami devices, though, are not remotely pocketable. Even just a SLIGHTLY smaller screen... and make the casing NOT significantly bigger than the screen... would make a couple inches difference. Like a Newton form factor.
And of course I'd demand OS X
Now, just because I want a 6" screen doesn't mean the market is large. But it is POSSIBLE to create successful new categories sometimes, and I think the market could grow if the product were done right (and priced right). This thing looks like it's too much of a compromise to be the groundbreaker with success beyond what other tablets have managed.
