Hi, About to buy the new MB 2.4Ghz, assuming I can get my hand on one at the local Apple store. Thinking of getting the 250GB HD, and potentially swapping for the 320GB at some later stage. Would like to check the price of a 320GB HD (that fits the MB), assuming I was to get it today. => Anybody knows where to find one ? I have no idea if there are some specs I need to be mindful of. Thanks for any help, W.
