It is larger... but that's the reason I gave up the i5. All they did was elongate the screen. Silliness.
I can't talk for you, but for me and many others, using anything larger than the iPhone is not comfortable.
To say that all they did was elongate the screen is silliness. They also made the iPhone faster every update, better camera, better battery, thinner, and now iOS 7 is a big step in right direction software wise. Finger print detection. Do they have to change the hardware/software design every update?
I also enjoy that they don't stick in quarter-baked or unused features in every phone they come out with. NFC sounds great but does anyone actually use it? Does it save time? Barely. Are the iPhones specs top notch? I don't think so, but iPhones have enough power and run efficient software that the speed especially in the long run will blow any other phone away.
If you want a solid device that doesn't need tinkering or getting used to, that works well out of the box, you get an iPhone.
