Linux seems not to ever suffer from viruses. And you can crash Linux if you try real hard and it starts up again reliably. Linux is far more reliable than Microsoft and same reliable before Mac went to Intel. Don't know how it is now. But its annoying not to have Flash on Mac Hardware. Or not be able to Play Mac Media on Windows as they come out of the box. Though VLC does largely solve that problem as a replacement for the native media players.
