Even bigger screen

Yes, the iPhone 5 is taller than the iPhone 4/4S and slimmer (18 percent thinner and 20 percent lighter), but it basically looks like an elongated iPhone 4. All that talk last year of a teardrop-shaped iPhone 5 turns out to be a fantasy (at least for now). And yes, the screen's larger (4 inches diagonally), but a lot of people wanted Apple to go wider and taller -- not just taller.

Probably not going to happen, but just thought we'd ask.

Chances of implementation: 10 percent
