Hey guys, I was wondering if anyone here uses one of those plastic covers for their MBP? Does this cover cause any cooling problems (or any hinderance to performance). I was wondering because I play WoW in native OSX and maybe it's my imagination, but I think it's running a bit slower with the cover on. What kind of framerates should I be getting? What do you guys get if you play? Also does it run faster in bootcamp. I heard it actually looks different though? Thanks!
