I have a Samsung 58" plasma downstairs, a 42" Pioneer plasma upstairs which is "my wife's tv", and a 32" samsung LCD in the bedroom. Plasma hands down has better pictures, but you do have to worry about burn in. The Pioneer has burn in on it, but you can only see it on white or really light pictures. To combat this, Samsung has screen scrubbers built in. Basically it is a pattern that scrolls across the screen and cleans out any burn in. This varies considerably between manufacturers but usually from 20,000 to 30,000 hours. After this time the plasma screen will only be at around half the original brightness. 20,000 is 833 days or 2.3 years of continuous 24-hour use. Or if you use it on average of 30 hrs a week(3 per day M-F and 15hrs Sat-Sun), that would be about 13 yrs of good service or round it down to about 10yrs. I dont know about you, but if I get roughly 5-6 years of service from my bigger TVs, I am happy. I have had my Pioneer for over 3 years and it still is as bright as the day I bought it.
