Not Really
The new MPB doesn't get nearly as hot as my old roommate's from two years ago got, I think his was just a normal macbook though, or maybe even a powerbook...I'm not for sure. That thing would actually cook your leg. I can play WoW on mine and it gets warm, but not too hot. The only place it really gets hot is between the F1, F2, F3 keys and the monitor. That little band of aluminum there gets real hot!
