Build quality is good not the best though and the iOS can very easily be beat, depends what you want out the phone. If you want a phone that is idiot proof then an iphone is the way to go but if you want to be able to customize it, add storage, change the battery, or want a bigger screen then stay away from the iphone. They make it idiot proof because a lot of people don't know what they're doing and just want a phone that looks good and works well which is understandable but doesn't make it better, I believe it makes it worse since they are taking the choice away from the customer.

EDIT:Spelling, and forgot to say that I wish android phones developers would put better DACs in their phones, the Iphone has pretty much all phones beat on the market for audio quality via headphones -at least out of all the phones I've personally tested- while HTC has better speakers in their phones.
