As far as hardware issues go, I've had my Evo since it's release on day one. No problems whatsoever so I can't vouch for those that have. My wife got her Epic on 8/31 release day. It's already gone back for a replacement; the capacitive buttons (back) worked when it felt like it. The keyboard is always moving in your hand so the phone does not feel solid. The GPS is at least two blocks off and that is with cell tower assist (hardware vs. software) who knows. The screen? I don't understand the ohhhs and ahhs frankly. I watch movies, do text editing and all the thngs that a smart phone can do and believe me "size matters"! As far as the UI, I dumped touchwiz day one and Sense on my Evo for that matter. Launcher Pro Plus on both and my Evo is buttery smooth while the Epic has noticable lag. I've literally spent hours with both phones. I honestly tried to like the Epic ($450 + out of contract makes you want to love it), but the wife had to have a physical keyboard. And another thing, about that keyboard..you have to be a contortionist to use it for things like punctuation, capitalization etc. With Swype, I type three times as fast with very few errors. I don't get it. Now I'll be the first to admit I am a fanboy of the Evo, in my opinion the baddest phone on the planet but as I said earlier, I wanted to like the Epic. Looked forward to playing with it but it does not compare to the Evo end of story.
