Hi, I want to purchase the 17 Inch MBP...Question though. I want to get the standard version with the 1GB of RAM, but what happens if I want to increase that down the line. Is that possible? Also, will that conflict with what I heard about how the RAM has to match for the Core Duo to work its best? Sorry, I don't know enough about what I just said to know if that made sense or not! Thanks!
