Hi I'm getting one of the unibody Macbooks, however I'd like 4gb ram. I would like to ask what other computer/laptop can use the Macbook's stock ram? The difference in price from the 4gb is the same as upgrading myself, but if I do it myself I'll have spare 2X 1gb ram from the stock laptop. If there are no other computer/laptop that can use the stock ram, I might as well upgrade during the order as the ram will be lying around. Any help would be greatly appreciated.
