The all but the sink device will happen but it is not expected any breakout ranaway success product of the same type to occure in atleast 5 years.
E-paper display and soon to be mainstream thin OLED display still have a long way to go. Screen technology, device size / thiness and the all important Battery (which drags down ALL mobile devices.) needs to be in perfect balance. WE have the CPU capablity / touch screen is improving, but not battery, there hasn't been much leap forward for recharge batteries, fuel cell is still struggling to massive production.
Whoever produce a powersolution for mobile devices such as iphone that allow it to last more than 2 weeks percharge on continous power on, plus control its weight to be under 80 grams is expect to be up for the Nobel price!
I expect some expensive devices to appear in 2013, but certainly not 2011.
