I've had the phone for a little over a week and am madly in love with it. I'm coming from an un-rooted Rezound, so I really love Google Now. A couple of days after I got the phone I left on a trip. Having the flight and rental car information in one place was pretty handy. It even had the directions to the hotel after the flight landed.
The phone is lightning fast and the call quality is great.
The camera is incredible. I'm still trying to get the hang of Zoe, but everything else is great. I love the front camera countdown and the panorama update. The color reproduction is pretty much spot on and the HDR is a big improvement from Rezound.
The battery life has been good as well. I bought a backup which I only needed once, and that was after 9 hours of heavy use, tons of photos, extended use of GPS and screen set on auto.
I also am enjoying the remote feature. It's a fun little app.
Lastly, thank you HTC for releasing HTC Sync for Mac. It's made transfering music and photos so incredibly easy.
