"They have to be recharged or refilled." - False

Plasma display screens are composed of millions of tiny Vacuum Tubes, which do not require maintenance.

"They last only a few years at best." - False

Pioneer Plasma displays have been working around the clock for years in airport terminals.  Expect your Plasma TV to last as long or longer than other TV's.

"They can be damaged by stationary images." - True

Only LCD and DLP technologies are immune to this, but neither one comes close to the life-like picture quality of a good Plasma TV.  "Screen burn" on Plasma TV's can be prevented the same way it has been prevented on CRT Televisions for the past 50 years...

...simply avoid prolonged viewing of stationary images.
