Here's my brief review after 2 days of using it:

I will only stated the cons, as others is GREAT/AWESOME/whatever you call it! 

1. The proximity sensor problem, it doesn't work well as it should be, the screen needs to be adjusted perfectly when you're talking in order for the proximity sensor to work, you can try use white themes, then while you're talking see yourself in the mirror holding the phone, you'll find sometimes your phone screen will not turn off as it should be while you're talking. I think this is hardware problem.

2. Sometimes (yes, sometimes) you'll find the screen flicker when you're scrolling/touching the screen. Noticeable when you're using white background. But this only happens certain times. I'm not sure whether hardware problem or software, i have read on the net, some said having this problem as well.

3. The battery life is not as good as others. Maybe because its just using 1300mAh battery. My test it only last about a day (25hrs), this is without 3G on.

That's the only letdown that i have with this phone so far. Other than that, awesome! Camera can consider as okay for a 5MP shooter, HD video recording is awesome, call quality is superb as what you can expected from nokia. Internet browsing is super smooth, screen rotation super smooth, everything is smooth because it's a windows phone. haha! this is why i left android. Single core can do a great job unlike android needs a dual core to be smooth.
