I currently have an Epic and LOVE the screen and speed. I'm being turned off by the keyboard to be honest. It's pretty easy to move and I find myself almost sliding it out by just hitting the power button. I'm thinking of moving to an Evo. The community seems much developed. I have a few questions though, How's the battery life? Do I need to root to not experience lag, or is it just as fast without rooting? Anything I should know?
