Heating is an issue with the Xbox 360's (and a huge issue with the PS3). After playing and switching back and forth between gaming and movies, it will start locking up on you. The simple solution is to get them 3rd party cooling fan setups, they will help keep it cool, but you do get alot more noise from them.
I too am a Playstation junkie, just can't wait for them to release there revision models to fix all the crap that's wrong with the launch model... ooh well...
