What are the odds of the MacBook moving to a Merom Processor in Sept. Oct. ? I am looking to buy a MacBook to replace my aging 667Mhz PowerBook G4 but i'd really like the new chip inside to make it a bit more of a speed demon. Am i dreaming in asking for this or am i going to be relegated to buying a MacBook Pro and selling my iMac G5 and my PowerBook G4 and just getting a single Intel machine?
