Plasma life (actually, it's hours to half brightness) was about 30k hours nearly 5 years ago. In 2003, half brightness avanced to 60k hours. When Panasonic rolls out their 8th generation models (the 8UY commercial series), half brightness will be rated at 100k hours -- equal to flat panel LCD. And even at half brightness, the user menu provides controls to account for this fall-off in light output.
For 30k hours half brightness, that's 4 hours per day for 20.5 years. Who keeps displays for 20 years? The average display is replaced about every 7 years.
Now, are they still susceptible to burn-in? Yes, but the advances of each generation makes this issue less of a concern.

Who keeps displays for 20 years? I try to! - mrspindlelegs 05:39:49 02/25/05 (9)
I don't know where this "7-year" average comes from but the vast majority of people only replace displays of any type when their current display breaks down and is too expensive to bother fixing. My Sony KV-27 series TV set is 8 years old and does need to be replaced because the CRT tube is going bad (one electron gun went weak). If the tube was OK, I'd run this baby into the ground as long as possible; it may not be HD in picture quality but it is damn good when fed a signal from DirecTV. I'm still going to try and run this set a bit longer because the new digital sets are not nearly as reliable as the old analog sets (yet). Further price drops is another incentive to wait on HD sets too.
As for the other displays, here is how long I've had them:
NEC 13" VGA Monitor - still going strong since 1989 (~ 16 years)
Mag Innovision 17" Monitor - 12 years old but is starting to show signs that the power supply is on shaky ground.
Hitachi 13" color TV - this is at least 25 years old and going strong.
If it ain't broke, don't fix it.

    Was a Huge sony console I got "free" as a premium for putting a bank CD away for 5 years. The fixed interest rate was 10.75 %. So the date was about 1980. It finally died in May of 2004--never had a single repair-- and I got the new Sony 46 inch RPTV then.
    I don't expct this one to last that long.
    Interestingly, in terms of overall size the 46 incher fits the space the old console vacated very well, and I think most people who owned a pecan grained console would be happy.

      That old Sony of yours is a fine looking piece that blends well with furniture. My parents had an old 1980's Hitachi console TV with the wood enclosure that never actually died. The picture just got worse and couldn't be adjusted so they finally swapped it out last year.

        While staring at a dead TV set and seated on the sofa on "the Culhanes of Cornfield county" as they dont have electricity yet.

        Sadly that Sony went to the recyclers, pecan veneer cabinet and all!
        Thankfully, the new one fits the old space well (above)

- it's worth replacing CRTs that are more than about 10 years old... - Sam M 08:41:38 02/25/05 (2)
  just because the level of radiation of the newer CRTs is MUCH lower than the old ones....
  - There are a lot worse things to worry about than CRT radiation emission. (nt) - mrspindlelegs 12:18:53 02/25/05 (1)

      Isn't that why Mom used to always tell us not to sit too close to the TV? ;-)
