I think what you mean is:
"I've been consulting in Windows technologies for companies for a quarter of a century and I have never seen a Linux workstation anywhere".
The first Unix (properly Unix, probably Solaris) workstation I saw was in the chemistry department as an undergrad (or maybe even doing a tour on university open days). I'm now in an office surrounded by people working on Linux (with an L) workstations and about half of them also have Macs (used as a Unix platform). The type of software we use largely does not run on windows, or at least not well. I've got Windows in a VM if I find a need to use MS Office. Or to put it another way, Linux desktops definitely exist.
