as a nexus 4 owner, I can say it is cheaper but not better.
technically, just about everything about the One is better than the n4 so I don't even know where ppl come up with this stuff.
if the development for the HTC One picks up, I would EASILY trade in the N4 + cash for the One.
What makes the One better? I'm in the market for a new phone and thinking of jumping from iOS to Android so it'd be nice to know benefits of the One.
