I was wondering if any of you have your MBP on continually and how it does with heat and performance. I am thinking about buying one to use as a mobile media center PC, namely sort of what I would use a mini for to hook up to my 1080P LCD TV (WoW on 52"!) but be able to remove it and use it around the rest of the house/travel etc. So, when it is hooked up to the TV I would like to just leave it on so that I can wake it up with the remote or bluetooth mouse/keyboard. I have heard about heat with these units and wondering if anyone has problems leaving their laptop on all the time.
