So I just purchased a new Retina macbook for school. With it always being in a backpack I was worried about scratches or whatever else from being inside a backpack so I purchased a Speck case for it (a clear see-through design). However, I noticed while the case is on, the laptop gets kind of hot. I've read a few threads here about others concerned about heat, particularly at the bottom of the unit. Most threads see this as a non-issue but it does get a bit concerning while being used in my lap. However, after a few nights of testing without the case installed, I noticed the heat on the bottom of the unit is drastically reduced. Has anyone else noticed the same issues? I'm thinking of disregarding the case if the laptop operates at cooler temps for a fear of the laptop having to work harder than it should thoughts?
