Today's generation of plasma TVs last a long time. With newer technology there is little chance of image burn or other problems that have plagued plasmas in the past. Expect it to easily last 5-10 years.
If lightly cracked the gases in the panel would seep away and you would quickly see a "dark blotch on screen" OR it is simply a cracked front glass of the panel that can withstand a beating (I threw a Baseball at it at 30mph and didn't crack a front panel!).
It depends on the half life hour rating of your TV. Some old models are just 30,000 hours but some newer are 60,000 hours. This means that you will slowly lose 50% of your brightness during that time.
Panasonic just announced a 100,000 hour TV. This means that you can watch 6 hours of tv a day for 40 years before it dies out. Obviously that time is tabulated depending if you watch more or less than 6 hours.
Keep in mind that a standard television loses about 30% of its brightness after about 20,000 hours. Since this process is very gradual, the consumer isn't aware of this effect, except for the need to periodically adjust the brightness and contrast controls to compensate. Although the performance of individual Plasma televisions can vary, overall, as a product class, a Plasma television can deliver many years of acceptable viewing.
Great question and the answer to this is very simple. LCD tvs last a lot longer than plasma and the pixels on the screen don't experience burning. Plasma tvs at some point the screen burns out and is now no longer wonderful anymore.
Scientificaly speaking a plasma panel should last for about 23 years if and only if the unit is used a stable, 6 hours a day; everyday from purchase.
Plasma televisions do have a finite life. The phosphors that generate the image age as they are used. It is this feature that can cause "plasma burn", an effect that shows a permanent shadow of a static image that has been displayed for many hours on the screen. Plasma burn is an exceptional event and if the display is used for normal domestic viewing, then it should last for many years. As it ages, the image brightness may reduce a little but this is rarely noticed. It is quite reasonable to expect a plasma screen to last for five to ten years with normal viewing. Manufacturers rarely quote operating hours as there are many variables that affect the life of screens.
Yes the prices have and still are decreasing on these TV's. Plasma and LCD screen televisions have dropped dramatically in the last 2 years and will keep dropping as newer models come available.

LCD televisions will typically outlast there Plasma counterparts.
It's the nature of the beast. Computer technology changes at an extremely high rate of speed. where as CRT LCD plasma and other screen technologies, change much more slowly. +_+_+ It's the nature of the beast.

LCD TV's last longer than plasma TV's.
One major drawback to a plasma screen television is that they are very fragile. They must always remain in an upright position (even in shipping) which sometimes the consumer cannot know. They are also very heavy. If your wall mount is not mounted properly for the weight the television set will come crashing down to the ground. One last negative thing about the plasma tv's is that they suck huge amounts of electricity. If you are trying to cut down your energy consumption this is not the television for you.
