I currently have a iMac C2D. I have 2 options 1) add a MB C2D now 2) wait for an update led screen/santa rosa. I use my mac for itunes, iphoto, imovie, surf the web. update: I got the macbook but now do not use the imac. I generally do not take the macbook to work all pc's. I use it on the couch which I love and used to do with my powerbook. The question is should I return it due to the fact that I am not using my nice imac and $1,200 is alot to surf the web from the couch.
