I got excited about the eDGe because it was the first 10" android tablet-ish device announced, the first android e-reader announced, and the first android e-paper device announced. It kind of gives all of the benefits of those things (which also retaining the benefits of a color LCD android device, for media viewing and such). Low power consumption of an e-paper device, e-book reading on a decent screen size, and just about everything I do on a netbook (web pages, web apps, notes, ssh, vnc).

I kind of like the "dual-book" idea (OLPC2 concept, MS Courier concept, etc.), but only if it's done right. In retrospect, I don't think the eDGe is ideal in its dual-book implementation "ideal" would be if I could use the non-color screen as a virtual keyboard/trackpad, so that it becomes a sort of virtual netbook ... but you can't do that on the eDGe, because the non-color screen isn't touch enabled, only pen enabled. It wouldn't be as good as a real keyboard, but it'd be somewhat useful, I think (the "virtual netbook" idea is a "nice to have", not a "must have", to me, though). Also, the OLPC2 lends itself to being used as 1 large screen. The eDGe doesn't (but that's actually a minor misfeature). So, the dual-book format is interesting, and the eDGe uses it to _technically_ (but not elegantly) meet my desire for both a color LCD and a low-power e-paper display.

My main disappointment with the eDGe is actually the lack of video-out. I want to be able to hook it up to a KVM (or maybe even a TV) to use for various other tasks.

The Adam, with its pixelqi display, gives you the same things (except the virtual netbook format), plus it has video-out. I don't need the pen input, so that part isn't a negative to me. It was the first device to be announced that really hit all of my bullet items (the eDGe hitting almost all of my bullet items, enough to be compelling), including the pixelqi display.

An Android version of the HP tablet (which is rumored to be coming) is also an interesting/compelling device. Probably one step down from the Adam, if it doesn't have a pixelqi display.

But, if what you start with is: "I want an Android/Ubuntu/Maemo/Mac-OS-X (not iPhone-OS-X) 9 or 10 inch tablet", with LCD for color, and e-paper for reading and low-power consumption, and KVM ports for use at a desktop (or at least USB keyboard support, for fast typing in a meeting or classroom) ... then you can see how those 3 devices all sort of scratch that itch quite well. And it should also explain why the Adam displaced my interest in the eDGe. The only thing that that the eDGe might do better than the Adam, at this point, depends on just how compelling the eDGe's e-book store is (and whether or not I can get those same titles through other e-book stores).
