Generally this is a good rule halo. But Mac OS X is a big exception. 5 years ago I predicted that MS would be gone and OS X would be the only widely available user friendly operating system (of course, the various Unix derivatives are going to survive and be healthy, but niche, players for many decades to come.. in fact Mac OS X is built on one of them, Mach 3 Unix, and is dependent on this programmer base for it's depth and stability). I was obviously wrong in that prediction but "better late than never".
