Linux is replacing Unix, and there will be a user base for that for years into the future I think.

I do agree that it is possible to royally screw up an XP install within a very short period of time, although I'm not sure how relevant to the current discussion this is. I worked with one particular individual, who, without getting into specifics, was by his very nature less computer savvy than the least computer savvy among us, less so that even my mother. From a clean install of XP, it would take him about two or three weeks to get his system to the point that it would take about five minutes to load XP, and then error out. Eventually he managed to kill his net connection somehow. To make matters worse it was an early model E-machine with questionable components, and doing any sort of maintenance on one of those is a nightmare.
