After getting my MBP, I remember something my friend once said. He has a 2010 15" MBP, and he is super anal about anyone using it, let alone himself. The thing he is most anal about is carrying the laptop around. He says you need to close the screen and wait for the light to stop blinking before you move it. He freaks out and says that you'll scratch the HDD if you don't. Now maybe I'm just ignorant on this subject, but from all the PC Laptops I had I was always carrying them around and I never messed up them. So is he full of bologna or in the right?
