I'm finding the battery life to be excellent, much better than my Trophy. I like the look of the phone. The speakers were better on the Trophy, but it's not a big deal. Camera is definitely much better than the Trophy's. Data Sense is cool, it's nice to see how much data each app or process uses as well as the difference between WiFi use and Data use. 4G is a huge upgrade over 3G, and I get it at my house, which is somewhat out in the country, although I still use WiFi thanks to the data cap and WiFi is less demanding on the battery.
I used Nokia Drive yesterday, it worked just as well as I could hope. It used a good bit of battery, but I'd normally have it plugged in in the car, I just wanted to test it out. Build quality of the phone is very good, and the removable battery and microSD slot are very nice to have. Screen resolution is fine most of the time, sometimes it stumbles on small text (badly rendered text, I'd say, not really the phone's problem), but it's perfectly fine for me. That's my mini review of it.
