As a Mac user (and someone who spends most of the day in Xcode), I feel lucky to have a machine that generally works most of the time and I don't need to defrag it, virus-scan it, memory-clean it, watch running processes for free RAM, and so on and so forth. So, I feel really bad for users who feel duped into downloading things like this -- they get a subpar computer as a result, and they totally don't have to.
