You can fit a bigger screen into the same space with the bezels removed. There is no compelling reason to have a 4.7" screen when a 5.something" can fit in the same form factor.
I did think it was odd to have such a large, ugly bezel on a contemporary phone, especially one from Apple.
I absolutely want a smaller device, and the trend towards phablets becoming the new "normal" really annoys me. But why does this have to be so damn ugly?!
