I am looking to purchase a new MacBook but I don't know which one to get. However, I'm still in my undergrad. (Anthropolgy major ) I plan to enroll in the post- baccalaureate premedical program in the future. Should I get the new MacBook or the 13 in. MacBook Pro ? My needs are iTunes, Internet and Microsoft Office. I need one that will use in my undergrad years and that will last me through medical school.
