Burn in is not eh problem it was three years ago. And yes viewing angles are better. If your going to watch TV in low light because plasmas have reflective screens you shold look at the Panasonic TH-46PZ800U which is review here at CNET. FYI the 650 has a reflective screen while the 630 does not.

Nothing beats going to a store and looking at bothe TV's and judgeing for yourself.
