Ya,... depending on whether or not you'll be playing online games that aren't Mac compatible, you'll have to face the decision of which type of laptop to get... a Mac, or a PC. Also, another benefit to the Mac is that they make all of their own parts, so you know that they will last long, unlike HP computers.
If you are also using it for everything else, along with POTCO, I recommend the Mac Book Pro (sadly a little expensive).
