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.
