Looking for feedback on HTC One

I'm looking at getting a HTC, I can get one unlocked for $499 from HTC and I can get $330 trade-in for my old phone. Yeah I know the HTC One 2014 announcement is coming on March 25th but I'm not wanting to spend the probably $600+ for it! not to mention I think the 4.7" screen is my sweet spot.

Anyone have major complaints?
