Ill keep it short and simple. I am a long time MAC user, however I just recently bought my first 15'' i5 MBP and Im wondering what the experts (you guys) use with your MBP that you cannot live without? For instance, I just bought a Incase Neoprene case for mine, but im wondering what you guys use as well? Anything from cases, to cleaning utensils, hard drives, anything! I figured it would be insightful for myself and others! So what is it?
