I recently purchased an iMac (1GB RAM) and because I wanted to upgrade it to 2GB RAM without paying the Apple RAM tax, I also bought 2 x 1GB RAM sticks from Crucial at the same time. When both orders arrived, I found that there was only 1 x 1GB RAM stick inside the iMac (instead of 2 x 512MB RAM sticks). If I knew that, I would have just ordered 1 x 1GB RAM stick from Crucial. So my question is.. does this apply to MacBooks as well? For example, if I buy a MacBook with 2GB preinstalled from Apple, will it actually have just 1 x 2GB RAM stick, or will it have 2 x 1GB RAM sticks?
