I doubt the iPhone Screen will get larger, most users would be happy with that size and for anything bigger they have the iPad now, plus all they've really done is keep up with the market since the 3G, there was nothing ground breaking about the iPhone 4 to me, Yeah it is a good phone but there is a lot wrong with it too, mostly the price then there is the issue of I think everyone has or knows someone who has broken an iPhone screen, and then Apple have the bright idea of putting a second glass panel in the back. The reason iPhone does well is because it's Apple selling it, the same people that can convince you to drop three grand on a desktop that you could do with half that money on a PC and that for some reason your mum needs and iPad when really she's going to use it for the free version of FruitNinja and read a couple of books on it before she realises she got an expensive digital photo frame for mothers day. I personally think Android is exactly what the market needed, open source software just gets better and better because Google have basically said okay guys and gals heres what we've got, what do you think we can do from here and they wait a few weeks and months and they've got thousands of developers tinkering and modding and then they reap what they've sewn which is all the best bits for the next update and it's what the users want too because it's by the users.
