I am soon about to get a MBP with stock 2GB RAM. Apparently it takes 3GB? I'm guessing it's 1 x 2GB plus 1 x 1GB stick. Is the stock 2GB configuration 1 x 2GB stick or 2 x 1GB sticks when you order it from Apple? The reason why I ask is because I have 2 x 1GB sticks in my MB and would like to take one from it to add to the MBP so it is maxed out to 3GB.
