I got this HUGE device on Friday and have to say I LOVE the screen's color and shrpness. A 5.3 Super Amoled screen with 1280x800 resolution is perfect to watch Netflix and surf the wed for long periods of time. I wouldn't use it as my primary phone, but as a second phone it's perfect.
Pretty good battery life, and it uses ATT's fast 4G network. With the large screen and 4G connection, you will fly thru your data plan quickly. So you should consider getting a larger data plan, which ATT have recently increased the prices of...not really happy with that.
