I have had my Incredible S for a week now and I do not regret paying for an unlocked, unsubsidized phone off of Ebay at all. This is my second HTC android, my little Aria is a year old and I wanted something bigger, but not 4.3 inch bigger like the HTC Inspire, so the Incredible S fits the bill.
For my daily usage, the battery life in this thing is 'Incredible'! I have both my corporate Exchange email and Gmail in 'push mode' sync, run with both Wifi and BT turned on all the time. I frequently am checking Facebook and LinkedIn and some light texting and by the EOB at 5PM I still have about 80% battery left.
