I just got the Epic and the speed is kind of mindblowing. Compared to all the other Android phones I've used this one is so much more responsive and it's still on 2.1 too which is even more amazing. Speed wise this thing completely blows the Evo out of water. It almost seems more responsive than the iPhone 4 to me honestly. The contrast of the screen is amazing. I think the Epic is the best Android phone so far.
