Man. Hopefully these come with some kind car-like exhaust heat shield between the keyboard and everything else. I tried playing games on my macbook pro, and while it ran fine (guildwars 2, a few years ago) the machine got so blazing hot that I had to play with an external keyboard.
After a few days of doing that I figured that having the laptop that hot for extended periods of time wasn't a good idea and quit playing. Probably for the better.
