Hello everyone, I recently ordered the black macbook, 2.4ghz, 2gb ram, 250gb hard drive to use for university. Now, after buying it I have heard alot about its heat issues, and how it can be VERY warm. Should I be concerned about using it for long amounts of time? Is it bad for the laptop components to be hot? Also, I will be using the macbook off my lap quite a bit, in bed, watching TV, etc, is the heat bearable? Cheers, Eric D.
