iPhone 5 all the friggin' way baby! No other phone holds a candle to it.
Really, I always hated all things Apple, but credit must be given, when credit is due.
For me, the phone's merits come from how good is it as a phone, and how good is it of a camera, both for video and photos. No matter how big phone screens get, they are still not big enough to comfortably read e-books, and the way things are right now, when you have a small screen, there isn't much difference reading on the iPhone as opposed to Galaxy 3. Besides, where the Galaxy 3 wins in size, the iPhone wins in clarity and contrast.
And videos? Seriously. Ask yourself, how often do you watch videos on your Phone? In all the years I owned smartphones, I never watched anything aside from you-tube, and even that, very rarely because of prohibitively high data rates.
Now, the most important part. The two most important features in any phone. It's performance as a phone, and camera.
Unlike some Android phones, the iPhone will NEVER, EVER freeze, crash, slow down, lag during number dialing or glitch in any way. It simply works, and is always ready every time I need it to be. Both talk and speaker quality are always stellar, and do not degrade with age. (Extremely important for me)
And the camera? Please. Don't even try to tell me that your camera on the Galaxy 3 is as good. It's not even remotely close, no matter how much you want it to be. And what if you are shooting at night or indoors? Fuhgetaboutit!
The camera on my 4s is so damn good I find myself never using a regular P&S ever again. And on the 5 it'll be even better!
