I just bought it on Friday and I've noticed that it seems to be constantly warm, even when I'm just doing something simple like using Word. My old black MBP would get a bit warm if I was watching video or something, but for just normal use I didn't feel much heat. It's pretty annoying because I'm just typing and feeling the warmth on my wrists. Aside from that I love it so far, but this is bothering me more than I'd like. Is this normal or something I should be concerned about?
