I had an HTC Droid Eris and was very disappointed for two reasons:
1) THE worst battery life of any phone I ever had. I could not get more that 9 hours, even with bluetooth and wifi off. HTC has needs to fix the battery life problem before anyone should buy this phone.
2) while I originally thought the smaller size to be an advantage, it soon became evident that the smaller screen and accompanying smaller soft keys made it impossible to type without constant backspacing and correction.

Smart phones have bad battery life get over it 9 hours is pretty good. My battery went from 6 hours to 1w hours gotta let it break in man
