So it looks like Apple is going to improve iBooks and PowerBooks again. What I find interesting is that they're sticking with G4 processors. This is probably going to be the last time; G5s will be next I'm sure. Sources apparently have reported faster G4 processors, larger hard drives, and better graphics cards. Good stuff. I wonder if there will be any more physical changes, such as different motherboards. If so, we may be looking at a new type of memory that needs to be used and a drop in laptop memory prices as well. How nice would that be?
