Hi guys, here's the situation. I currently have a 13" Macbook from 2007 that suits most of my CURRENT needs, ie. surfing the web, word processing, iTunes, chatting, watching movies etc. Really the only thing it can't do is light gaming and audio editing with Logic. Long story short, it's failing, and it's getting replaced by Apple. I despise the current white Macbook though, so I'm paying the difference for a MBP. I'm starting college next fall, but I have no idea what I'll be studying in the long run. I'm hoping for this new computer to last me through the 4 years, whichever classes I pick. I know the specs would last me longer from the 15", but I love the form factor of the 13" (never seen a 15" Macbook before, only an HP which looks massive compared to my whitebook). Portability is a pretty big issue, since it will be traveling to and from class, I'd assume. The thing that worries me, though, about the 13" is the Core 2 Duo processor as opposed to an i5. If Apple hadn't offered to replace my machine, I wouldn't even consider the 15" because of the price. As it stands, though, I can get the 13" for $200 or the 15" for $800 (without Applecare, which I'll buy when I can get a student discount on it.) I don't want to get a 13" only to find out in Junior year it doesn't have the specs to run certain professional applications I might need to use. It doesn't have to run them at lightning speed (I don't have a job that depends on it), but to an acceptable degree. So which should I get?
