So far, it's working out very well for me. No trouble installing/running apps, and I'm more than satisfied with the way it works out of the box. WiFi connection works well, and I still have plenty of internal space so far after installing nearly half the apps that currently reside on my rooted LG Opt V. I did get a 32 GB PNY Class 10 MicroSD card from BB at $30 to help with app space + data.
I don't expect this to be an XboX 360/PS3 (or even my current ASUS laptop) in a small size, but the 3d, audio and video performance is more than acceptable for me, coming from the V. It's also nice to have a physical keyboard again. I had one over a year ago, a Samsung Intercept. That thing was a horrible POS.
I'll activate it on Monday, when my current $25 plan ends. But so far, I just love running anything I can throw at it. I'm not even sure I want to have this phone rooted...? Haha! We'll see...

Anyway, I'm recommending this phone to my mom, who wants to get out of a Sprint contract. It certainly eats her old Samsung Moment for breakfast, lunch and dinner!
