Build quality is flawless, I guess Amazon having delayed stock was a good thing as earlier models had build problems. The look and feel overall really shows HTC has learnt from their mistakes and is trying to get back on top.
Sense 5.0 feels a lot cleaner and smoother than previous versions, while I prefer stock Android, Sense 5.0 is actually something I don't mind using, it adds onto the phone quality and makes the overall phone feel great.
Speakers are great, and they are very loud, even on low volume. This is great for anyone who wants to play music out in the open or watching films. Compared to rear facing speakers, these make a hell of a difference.
Camera quality wasn't perfect initially but an update from HTC seems to have solved it by quite a bit. Not as good as some phone cameras in the same price bracket but colour wise it's more accurate. Low light shots are great as well, meaning I don't need to rely on flash too much.
Don't let HTC's past phones put you off this device, it's on a completely different level and by far one of the best phones I have ever had.
