Definitely interesting, although it'll almost certainly be less capable and more expensive than they promise, like most gadgets.

A couple changes that I'd make: I'd add a OLPC-like handle to the keyboard/dock in order to help stabilize it. I expect its screen is comparatively heavy and makes it unbalanced in netbook mode.

Also, I'd like a full-size SD slot (or two) and video-out. A 2.5" drive bay in the dock would be nice.

Things I particularly like: a second battery in the dock, and plenty of USB ports.

I doubt I'll be an early adopter, but I hope it succeeds.
