for me, it really depends on you. Do REALLY REALLY need the macbook/macbook pro NOW OR can you wait. If you can, by all means do. Me? I need a macbook now coz my wife just inherited my iBook and my Compaq is doing a no-display-when-powered-on kinda thing.

Don't care much about C2D coz the most probably you can get is around 8-10% more than what you have now on Core Duo. I'm really waiting for the TRUE 64 bit chip, which should be out sometime spring 07.
