Coming from a Dare, this phone is awesome. I just wish my accessories would arrive sooner and the battery would last a little longer.
I came from the Dare, to the Eris, now the X. You are gonna love Android. It just keeps getting better and better since I got my Eris in January.
Do a search here for battery tips, there are a few threads under various phones. All are basically the same. Keep GPS, WiFi use down. Updating widgets use 3G and thus the battery. Set sync for apps and email to longer duration... Tweek a few things and this phone will last all day.
