I was asked to get some information for a friend of mine who has a MacBook, black, 2.2GHz, 2GB RAM, and a 160GB HDD. He got a HD video camera, and would like to edit and make simple movies on it. He wanted to know if getting a PowerBook G4, the last-gen HighRes version, would be better at basic video editing than his MB, due to the discrete video card. The maximum he can afford would be $550, any suggestions, and he did say that was the maximum he could afford, no more, no matter what. Any suggestions?
