I agree also, over the years I have used different OS's by choice, because I
liked them better than others I had tried or they fit the job/purpose. I ran a
totally automated OS/2 system that ran 2 BBS's and a networked Satelite Data
Feed, now I have been running Linux for over 10 yrs, different flavors.

At work we have machines that run Win95 (Laser Drill) and (automated part
brushing system), WinNT(High Speed EDM machine), Win95(EDM machine) embedded.

We also have a newer Laser Drill machine that uses WinXP for the user
interface, Linux for system control, and an embedded WinXP inside a controller
for the laser system, so this has 3 seperate computers to make the machine
work.

This also proves that there is a place / reason to use many of the OS's out
there and not only for a desktop.

The best part is you get to choose, and with Linux the cost of trying out the
software is very attractive, and you have many flavors to try.
