I've had an Incredible for about a week and it seems to work fine. However, about two or three times a day (that i'm aware of; could be more, of course) the phone reboots itself. Out of nowhere (i.e., in my pocket or lying on the desk) it vibrates once, then the HTC flash screen appears and reboot continues to finish. I've added perhaps six or eight aps to the phone but otherwise not tinkered with it much. Gmail is my email account. (I do have the backup assist program engaged; could that be it?)
