I'm definitely switching to macs this year. I want a 20" iMac and my wife wants a macbook. There is a Mac store near us as well as compusa. I've seen some things on MacMall but I'm not sure where to get the best deal. I also want to upgrade the ram in both machines and don't want to get taken by the mac store. Are there good sites for deals on mac ram? Also, how hard is it to install ram on these two machines? I've done it on PCs but never on a mac. Thanks for any help you guys can give us.
