I've read up on both phones, had the salesman spiel for both, and one of them will be my next phone, probably by Friday. I want to know why I should not buy one or the other. As far as usage, in case that'll help, I'm a college student, so it's mostly a twitter/facebook/G+/internet/texting machine. I'm on wifi for most of the day, and I'm on Verizon (blame my dad's employer), so no colors on the Moto X and the One is still a recent device.

tl;dr: cons of the HTC One and Moto X.
