Hey guys. This is my first post on MacRumors as I recently discovered this website and found it to be very helpful and informative. So here's my deal; I purchased my first MacBook Pro in August of 2008 when I started college. I obviously love it but now I'm wanting to get a new one. It's an older model (2008) so I guess it's somewhat outdated (I am not extremely computer savvy.) There is a crack on the frame around the screen, it's very dirty, has "burn" marks on the bottom (not sure how they got there) and the battery is brutal. I'm very excited about the new Lion software but I haven't purchase it yet because I might be buying a new laptop (likely this weekend or bust.) I just want to know is three years too soon despite the problems? Should I suck it up and keep going with what I have or get a new one? I'm not very sure/specific of what I want other than a 15' MacBook Pro. I really only use Excel, Word and iTunes and the internet and I don't venture too far out other than that. Thoughts?
