Hello, I'm debating whether to purchase a stock 2x2.8ghz mac pro 3.06ghz 24" iMac or a topped out 2.8ghz macbook pro. As of now I'm using an old white iMac and it is just way too slow for what i need it to do. I am a college student and qualify for a student discount which lands the three options in about the same price range with the iMac being the cheapest. Currently I do a lot of video editing in final cut express and use photoshop quite often. I love the idea of a laptop but I already have an older compaq that can be used for basic tasks. Since this is such a large purchase I would also like to be able to use it for long time without it going absolete which is something I have run into with other puchases of mine. So which one should I get?
