the most successful disto i have come accross is Kubuntu and Ubuntu, but that is beside the point.
I hate people (especially Mac Fanboys) who complain heaps about how Windows is crappy and unstable, and not as advanced as thier precious Mac Os but in there household they have 2 Windows PC's compared to thier 1 mac. I offer to install Linux on thier PC's because they hate Windows so much. But they refuse. In reality, they need Windows but they dont accept it.
