Hello, I have a 2008 iMac, 2.42Ghz C2D w/ 3GB ram. I have been wanting to switch to a laptop for a while and have waiting for the MBP update. Now that its here, I am second guessing myself. Is it worth it to switch to the base 15" i5 MBP? I do a lot of audio recording and heavy use of Creative Suite. Thanks!
