I like to use my mbp while laying in bed. But this raises an area of concern about heat issues. Since I am not placing the laptop on a perfectly flat surface. I have a blanket over me and i have the laptop on top of the blanket, or I'll just lay sideways and have my laptop set on top of the mattress with the sheets on. Will this harm my laptop overtime? I don't want to find out that my internals are slowly frying up by using my mbp in bed. Does anyone have more info on this?
