I'm going to be purchasing a new MacBook Pro in the next few days (upgrading from a 2007 MacBook Pro 15"). I'm a college student but the money difference isn't an issue for me. I'm a nursing student so I dont really need to carry the computer with me at all times or to all classes and mostly would use it for typing care plans/papers, using the Internet, and for music. I really love the 13" size but I am more concerned I'll buy it and end up regreting I didn't upgrade to the 15". Based on my situation which computer do you tech savvy people think is the best purchase for me? Is the 15" just a better upgrade since the money issue isn't there or is the 13" more suited for me? Thanks in advance!!!
