So I used to be a PB G4 12" (1.33GHz) owner, who moved to a MacBook 2 GHz (Core Duo). The MacBook always seemed a little slow to me, but nothing striking. Then recently, I had a chance to work with a PB G4 15" (1.5GHz) and I just feel that it blows away the MacBook. It's only got 1GB of RAM while the MacBook has 2GB, but even simple finder functions and multi-tasking seem to be noticably slower on the newer, Intel based model. Has anyone else felt like this? Could it be bad RAM or something on the MacBook? I don't think that's the case, because it seems to behave about the same as the models at the Apple Store. I just feel like I'm going crazy, and can't possibly be right...!
