I've just recently purchased a new mac book pro. I also have a 2.0 Intel Core Duo macbook. I've been offered a powermac dual 1.8 for my macbook. I'm not sure if I really need two laptops. I need a laptop for work, but for home I just need somthing for imove edits and itunes. Does anyone know how the powermac compares to a macbook running the ilife applications? Should I trade the macbook for the powermac?
