I know Apple doesn't believe in market research or what people on general think what their products need to be like. But I think the overwhelming majority of iPhone users want a bigger screen for the next iPhone. Now Apple would be really arrogant in ignoring all these people and to continue thinking they know what is best for their users in terms of how big a phone needs to be. If they release another 3.5 incher, it could be their first misstep in a long time which could even lead to them losing some of their market share to their competitors. I sincerely hope they are humble enough to listen to their customers who actually buy their products and make them the success they are.
