Just bought one yesterday. I'm little surprised that there seems to be no reviews at all for this model anywhere on the internet. Overall I'm pretty happy with this TV except for its weak black level, which can be very obvious when all the lights are off. Unlike my previous Sony 60" EX645 which has serious dark corners and uniformity issues (I exchanged two EX645s and they ALL have the same problems) this Penny seems to be immue to all those, at least for the one I got. Picture is very clean and bright, motions are smooth enough to equal with the plasmas. Sound is just OK, I think Sony is doing a better job on this, but I'm getting a sound stick anyway so it doesn't matter that much.
IMHO nowadays HDTVs are all very similar comparing with each other, unless you're very picky on minor issues which can be very objective. For the $1.3K I spent I think it is a good buy, and I don't really care for the lack of 3D. If you can wait the E60 (scheduled to be released in 1Q) might be a better choice, except they don't offer 60" this time though.
