The problem with that is, going with the current trend, by 2014 Android phones will be pushing 7-8".![]()
I think they'll eventually hit a point where consumers will be turned off. 5" is probably the absolute maximum for a mainstream phone...maybe even 4.5". The average person is not a Fandroid clamouring for moar screen -- people actually have pockets and hands to think about.
ETA: If anything, Google Glass and the rumoured iWatch will help spur the trend toward even smaller devices. Why would people want to carry around giant slabs of plastic in their pants? (insert joke here, I'm too lazy)
