Hi, just wondered if the RAM for the previous model would work in the new model and if anyone has tried this? I didn't fancy the £320 for the 8GB when I ordered and now I'm waiting for delivery trying to get everything in place for the move over to the new machine. So if anyone has a good suppliers of RAM (UK)could they share a link please. And a good price for 8GB RAm for Macbook pro. Lloyd.
