Hi, i want to buy a the new MacBook Pro. i'm 15 years old and i want the 13 inch mbp. only i don't know which model i'm going to take. i'm thinking between the 2.26GHz and the 2.53GHz. This is what i usually do: - internet - msn - x-plane 9 (special mac game, only game i play) - watch movies - download music - mail - school (iWork) - take with me during holiday Which model is the best for me?
