I'm considering upgrading my RAM for my 2.0 Ghz MacBook. A few questions I want to ask: - How much performence increase would you get for the 1 GB vs. the 2GB? - Price: What do you consider a good deal for RAM (1GB and 2GB)? - Where: I'm looking for a good price and reliable customer service - How hard is it to install the RAM? Should I get Apple to assemble it for me? Thanks.
