Hi all. I've been using Windows (and DOS, egads) machines for quite a long time. This past year I found myself working at an OSX.3 machine doing some simple audio production (teaching a music technology course in public school). I've been thinking of buying a laptop for audio production (portable for live recording), and I've been up in the air about whether or not to go with an OSX machine or a Windows XP machine. After some recent frustrations with Windows, I think I've decided to go OSX, but I really have no concept of what the Apple specs I'll want are as compared to the windows ones. I've been poking around the forums and some people seem to feel that the powerbooks are just too slow, while others couldn't be happier. So, I guess I'm just looking for advice; am I truly going to be happy with a powerbook? At what mHz will I be happy? I'm trying to be on a budget, so I'm not going to jump on a 1.33 17"; I just can't afford it. Help this n00bie (sorry) get his bearings in this new realm. Also, in a slight tangent, so the G4s are motorola chips, and the G5s are IBMs? So, is Apple phasing out Motorola from their computers completely, or are they going to run two separate lines of processors?
