Hi, I got my new MBP today top end 15" one. I am currently installing a game in windows. All that is happening is I am posting on here whilst steam downloads something. The bottom of the laptop is ROASTING! on the left hand side, so right on my thigh as i am sitting down. The heat is comparable as to when i used to be playing WoW on my old 13" unibody macbook. Is it normal for it to be this warm when im not even doing anything intensive?
