As the title says, i am working on my macbook pro, watch movies, playing dvd's and listening to music while i work. The problem is, its really hot, not just hot its really really hot. My friend teh good friend he is bought me a hard cover sleave to which fits well. I dont feel the heat when using the sleave (it opens up like the laptop with a zipper) but should i be worried? is the heat going to cause a problem with the laptop?
