I don't know how hot they are supposed to get, but they will get very warm. There are no vents in the back like the Dell's, etc. So all the heat comes through the aluminum.

I was at an Apple store last night and noticed the ACD's were very warm to the touch.
 
Mine gets warm along the top, but I never touch it (except for now of course) so what's the problem?

Just want to verify that it isn't defective while it is still new. Mine also gets quite warm on the right side.
 
Mine is < 4 weeks old and yes, it gets hot. I actually believe it changes the temp in my room ever so slightly.
 
My 20'' ACD is pretty old, about 3 years, and it's always been warm. Pretty sure it happens to all of the ACDs
 
All flat panels, especially the large ones, throw off ALOT of heat. The 30" uses 150 watts, I'd say it should heat up a little, but unless it burns you, I wouldn't be concerned.

From the apple website:
Environmental requirements
Operating temperature: 50° to 95° F
(10° to 35° C)

But have you ever been to a big TV store where they have plasmas/LCDs along a whole wall? It's kinda like floor heating, but on the wrong plane. :D
 
We'll see if the new ones run cooler; will their likely thinner case designs cool them down or warm them up?

Good info to know about the ACD. I'm in the market for an ACD and didn't even think about the vent situation.
