So, I made a mistake and let the warranty on my previous gen. 2.4 160GB white MB expire. I did intend on getting apple care, but life got in the way. Anyway, I have so far upgraded the Ram to 4GB, so I'm thinking of buying a 2.0 so I can put the 4GB in it, if I buy from Micro Center there's a $200 rebate. Eventually I do want a UMBP, but I'd like to wait for the next cpu upgrade. So I'm sticking with a MB for now. I play WOW, use programs like Mathematica. I don't like the fact that I'd be going down in cpu speed, but I think the video improvement more than makes up for it. Should I do it? Should I wait? I'm also considering doing a trade-in for it with Powermax maybe.
