No not really, the question is not pointless.
Keep in mind each model and size within each brand will put out different amounts of heat, AND each brand (with all the other factors just listed) WILL change from year to year (or even running models changes).
Pick out the few models you are seriously looking at buying and then compare the temps. Even at different stores. TV's sitting out in the open will feel cooler than those sitting under shelves. Placing your hand top dead center on the back of the cabinet can tell you a lot. You can easily tell the difference of a couple degrees, and you can really tell the difference of 10,20,30 degrees. They can vary that much.
You will find the current 2008 Panasonic plasma's to be exceptionally cool - it greater detail the 42PZ800U runs about 20 degrees cooler than the Samsung 32A550 LCD which is very warm (almost hot to the touch).
Some of the 2004-2006 Samsung Plasma models would actually burn your hand they were so hot, their 2008 models are a lot better, but still vary warm.
Also, keep in mind a set that has only be on for 10 or 15 min. is not a real comparison. Try to make the comparison for sets that have been on 4-6 hours. If it is still cool to the touch then, then it should stay that way.
Our house is kept at 70 degrees 24 hours a day - It's Houston and that is to keep the humidity out.
All temps are estimates but with a thermometer - top dead center, and after 5 hours of playing.
42"800U - 78-80 degrees
Sony HD DVR - 82-85 degrees(inside of box stays about 112 it has two temp gauges inside)
Denon 1909 AVR - 102 degrees (considered by most to be the coolest AVRs on the market) - it puts out a lot more heat than the plasma but far less than the Samsung 32"LCD
