I'm looking to convert to a mac and I need something within the next month. My wife and I are just started grad school and new something asap. I'm undecided as to whether it is worth it to wait until after the wwdc. From what I've gathered it looks like there might be an update to a Core 2 Duo. Is this likely to happen soon, or should I just go ahead and buy the current model? Other posts have said that you can update the processor, any guesses as to how much would that cost if I bought the current model? Thanks for your help....I think I'm addicted to checking the forums and I don't even own a mac!
