I managed a whole network of Macs back in the System 7, Windows 3.11/95 days. Yes the Macs of that time where easy for newbies to use, but when the OS became unstable you ended up having to bin it and start again.

At least with Windows 3.11 at that time you could go and find the problem and fix it most of the time, because most settings were in a handful of text files. That changed with Win95 of course, with the registry managing to take on many of the same problems of a screwed Mac.
