Opinion: Open Source vs. Windows

How uniquely distinct this is from the UNIX realm where the operating system's very roots come from a component based structure (each component must do it's core task well and inter-operate with the other components). Back in the 1980s I was using a mainframe running a UNIX variant that had almost five hundred simultaneous users and never went down. I would then drive home, turn on my PC and encounter a number of failures and reboots simply trying to run one single program.
