Literally.
http://www.slashgear.com/ps3-vs-xbox...own-045051.phpJohn Davison of 1up found this out the hard way. He keeps both is 360 and PS3 in his entertainment center. They are both enclosed in a cabinet, which he knows isn’t good for them when they are running. Well, the 360 does just fine while closed up, but his PS3 heats up very quickly, so he must leave the door open when playing it.
Unfortunately his son decided to pick up his SIXAXIS controller and pretend to play along with his brother while he played on the Xbox 360. Well, he hit the PS button kicking on the PS3, and after a short while heated up so much that it fried his 360. Ouch.
This takes the console war to a whole new level.
