</span></font> Good explanation Rich. Unix was built for the riggers of
the Telecomm industry. You won't find Windows running the PSTN. Unix and
Linux are used where their needed for real time processing and the highest
reliably. Windows is a productively OS that is easy to use for non technical
people. I use both as do many of us. Each has there purpose. <br>
