... a tablet or slate with a rotating finger-loop. Smooth design is all very well if all you do is browse FaceTweet and prop it up on your thighs as you lie back in bed, but RSI is no joke, and not one tablet, slate nor netbook has anything even remotely resembling a comfortable gripping handle.
Something like a shoulder-resting arm that fitted into the back finger-loop, to support the slate-thing while allowing us to type with both hands would also be a brlliant innovation.
Humans really need three hands, but, absent radical gene-slicing technology, a simple triplet of indentations on one or more sides of these things might be helpful.
I am convinced the designers of these things *never* try to use them for real work.
