after using my P42X28 for 1 week++, and comparing to my past 2 gen of Panny 42" plasma (PX70 & X10)
I would say I'm very disappointed with this latest gen of Panny HD-ready plasma TV
First, the audio sucks big time, even my 3 years old PX70 has better clarity than this X28, the best is still X10
Second, the panel... feels like its inferior to the X10, but slightly better than the PX70... I play X360 games mostly on all three, and i notice some "image retention" on the X28, especially on those scene with bright items then switched to a black/dark background, you still can see the white/grey spots on the dark/black background where the bright item used to be
most obvious when watching the credit of a movie/game
I don't notice these "defects" on my PX70 and X10
Third, I can set a user-define name for my AV inputs on X10, eg: HDMI1 as XBOX360, HDMI2 as PS3, these features are gone in the X28!!

Fourth, less features comparing to X10, X10 can play AVCHD, X28 removed the feature
in Overall comparison, excluding price, I would rate X10 as top, PX70 as second, and X28 as the worst

gonna get a Sony soundbar to replace the horrible build-in speaker
