Re: folding away
It could have the shape that I'd like some to have to accommodate where I'd like to put it, based on some people behave on the phone. Nokia once almost got there if it wasn't for width.
That aside, all of this strikes me very much as gimmicks in search of a problem to solve, and by that I don't mean "how are we going to convince people to part with their money again". What is the point?
I can see the sense of a display on the outside, but that's a need that is also addressed by smart watches (I personally like the Samsung approach more than Apple's), and it is not a new idea either. Ye olde (well, by now) Motorola RAZR v3i had that already..
