[moved from another thread - didn't mean to hijack that] Should I be concerned with RAM or processor speed for 2 or 3 users? Our new rMBP will be primarily my wife's work laptop and require few resources. However, I will want to use it for iPhoto/iMovie/etc and my kids for games. (when she lets us near it!). Our current MBP is so slow switching users we never do but I want to have the option. I especially want my kids to have access without risking any of her work. Will more RAM or speed make a difference?
