I just ordered the Sony SDM-S51/B instead, same price after rebate and discount. The SDM-S51/B have a better respone time 10ms/20ms instead of 20ms/30ms, a bit brighter 250cd/m^2 instead of 200cd/m^2. Also the Sony SDM-S51/B with 0.297mm pixel pitch instead of 0.30mm pixel pitch.
The only thing bad about the SDM-S51/B is it doesn't have the DVI input, but would that make that much of a deal in a 15" models? Also it doesn't have the build-in speakers, but do you really use those sucky speakers?
So I think the SDM-S51/B is a bit better for home use to play games on.
