Engadget were handed a few pictures of this 7" tablet thingie today. I'm still not sure it's real. I'm probably wrong, though; Engadget have a habit of getting leaked Dell stuff that turns out to be true.
But that keyboard design makes me wonder. You can see that it is split and is supposed to be held in 2 hands while you type with your thumbs, right? There's a spacebar in the center, and it would probably be out of reach of most thumbs. In fact, I just pulled out a couple 7" tablets for a size comparison and I don't think my thumbs are long enough to reach that spacebar.
Update: the photos came from Tweakers, a Dutch
German tech blog. This design was a pre-production model from a few years ago. It was never released, but the design did eventually influence the Dell Inspiron Duo.
