I have been a PC man starting on DOS. Two close friends have twisted my arms put me under mind control and convinced me I need to convert to MAC. One went so far as bringing an old G4 to my house and set it up and left it. Now I want one. I realize PC people work on their computers. Mac people get work out of their computers. I plan on getting a Mac Pro. Does anyone think the quad cores will be released at Mac World? I am not computerless unless owning 5 PC's counts as computerless. Should I wait or order now?
