Hi, Our business needs to do some end of year spending. These purchases need to be made before 2008. We are looking to buy several 15" MacBook Pros. Do we pull the trigger now, or wait? What are the chances well get quad core mobile processors in there before 2008? I see the buyer's guide has been recently updated to say hold off if at all possible. We can wait till 12/31/2007, but not after. Thoughts?
