Well, I have a PC that allows for two Gigs of Ram, and I can't find a single supplier in Ireland (where I currently find myself) that can supply 1Gig Ram chips, the biggest they can do is 512. And I don't have a credit card to buy one on the net. So I just hope Mac users can actually take advantage of the 8GB offer, because just because the motherboard can take it, it doesn't mean it's available.
