I have a 27" base model iMac and i wanted to return it for a base model 15" Macbook pro. How faster is the iMac compared to the Macbook pro ? Will i be loosing a lot of power? Do you guys think I should take that route? I do video editing nothing really to fancy just HD video from my DSLR. Or do you guys think I should go with the base line model 13" Macbook pro upgrade the ram and install a SSD and go with a 27" thunderbolt display?
