screenf*ld in com, a hand reg from a few years back.
I do envisage folding screens becoming mainstream in couple of years. As far as the phone to tablet scene goes they will have to get the bulk and weight (not to mention the price) down to get iphone adopters on board, but i'm sure it's coming..I can even foresee a phone/internet screen opening out 4 fold (as and when required) If they get the technology right it will bring the handsets themselves right back down to a small package
Reminds me of picking up my iphone (version 1) on a pre-order and everyone saying NO Chance that will take-off, Who wants a brick in their pocket
