I picked up one last month when Aio had them for $79 (sadly they're only $49 now, so maybe I should have waited a bit more). But still, the amount of features it packs for the price is incredible. NFC, compass, front-facing camera, rear flash. Sure, these are standard on a lot of phones, but rare on the lower end of the spectrum. Its sibling the 520 doesn't have any of those things. It even has HAAC mics, which is supposed to be a "flagship feature." After popping in a 32GB SD card, storage is no longer an issue. Plus I love the way it looks. I'm definitely in love with it.
Sadly 8.1 was a horrible experience for me. The amount of lag was insane and the battery wouldn't get me through half the day. But I just did a hard reset this morning, so we'll see if that clears things up. So far the lag appears to be significantly reduced. *knock on wood*
