Heat is pretty easy to check, just like anything else, I am guessing those who DO complain are in the minority. Tint? as much as I have tried to check the pictures posted, I really can't see what the issue is, guess I better check my vision I do plan on loading the programs that I will be using. X-code Blender 3-D Maya Adobe full suite. might run 2 of those at the same time, see how it performs. since this would be my sons FIRST Mac, anything in particular that we should really pay attention to? thanks.
