I also have had the HTC Vivid phone for about a week now. After doing some research, I found out that it actually does have the 1.5 GHz duel core processor, but AT&T is under-clocking it down to 1.2 GHz to save power. Battery wise, I'd say it's the best HTC I've owned to date. I am a heavy user, using the wireless network which is always on, Bluetooth always on and it's rooted with developer apps installed. It's not without the usual 'bleeding edge technology' bugs of course, but so far these are minor. Some of the new phones have been reported as having dust _under the screen_ presumably from not being sealed properly at the factory. Also some of the screens have been reported as having dead pixels, so be sure to check that and get yours traded out asap, *IF* that's the case. Overall, I highly recommend the Vivid.
