Think of each operating system as a line at the grocery store.   Even if
one of the checkers is slow or a customer can't find her wallet in her
purse, or there is someone buying booze that needs an approval from a
manager, there can be another queue without that problem.   That doesn't
necessarily help any given individual who's already committed to a line,
but in aggregate it does help everyone to have more lines.  There's also
the possibility of super-linear speedups (or synergies).  For example,
cash-only lines.
