same here, for me it mostly depends on what the macbooks will have to offer compared to the pros. And how cheap are they. I also don't think I will buy immediately, will wait prolly a week or so till reviews start coming out.
My current and primary computer is a powerbook G4.
Pretty soon after I got my Mini (Linux switcher), I decided to get a MacBook, but I saw from the Buyer's Guide I should hold off. SOOOO glad I did, the new MacBooks look awesome.
