rubicon, G3 to G4 is more like P3 to P4, in my opinion... I, too, have heard the 12" powerbooks got a bit warm, but that's all... as for X, I'm not sure how I feel about you saying that the UNIX shell is bringing it closer to the windows UI... Any properly zealotus mac user will protest that one. Unix != windows. CLI != windows. when a start menu appears, then I'll agree with you.
