I'm going to buy a Macbook when I'm in the US in a few weeks time. I want to buy 2Gb of ram to take with me and install right away. My question is this. If, although unlikely, Apple change the processor to a core 2 duo between now and me buying my Macbook will the 2gb of RAM still work O.K. Sorry if this is a stupid question, I just need to be sure before I buy the RAM.
