Hi, I am considering buying a 2011 MacBook Pro. I will be a freshman in high school next year and need a good laptop for school. However, I do not know whether I should purchase the 13 inch model or the 15 inch model. The following would be my primary uses for my MacBook Pro: -Note taking during school -Surfing the web (Facebook, mail, etc.) -Microsoft Office/PowerPoint -Playing games such as The Sims 3 -Occassionally GarageBand, iMovie, etc. Also portability and money are factors in which model I purchase. But I am used to a 22 inch iMac, so I'm afraid 13 inches will be too small. Any input is much appreciated! Thank you!
