I'd definitely go for the HTC ONE.
My old HTC still works like a bomb, and I'm starting to dislike the cheap feel of my S3.
Agreed. With tech specs all the same I choose the phone who's screen wont crack the 1st time its dropped.
That dismisses Samsung from my experience (and that of almost 10 people in my office). My HTC OneX is still fine after being dropped several times - whats the opinion on Sony in this regard?
