Heh, this inspires a neat little bio.
I had access to then-usual computer-related stuff growing up as a teenager in the late 80's/early 90's (C16, C64, Amiga, DOS/Windows on 286/386). One of the nicer things in that environment was a PostScript capable laser (well, LED) printer. At that time struggling with PageMaker and the likes, the possibilities of a page description language fascinated me.
Later, but still in teenage years, I came across NeXT(STEP) - first through a friend who had one, and its manuals and TeX documents out that PostScript printer like nothing I'd ever seen (done in-house) before. I was hooked. ;-)
A NeXT computer then became my daily driver through "college" and university, where at the time there also were Unix workstations by HP, Sun and SGI. DOS/Windows was all happening at that time, and it always felt to me like the VHS of operating systems - the technically worst implementation taking the market share.
When Linux appeared on the scene, I was obviously interested. The first distro I remember was SLS, followed by SlackWare and Red Hat. Mostly for communication/networking (UUCP, PPP, eMail, Usenet, IP connectivity, ...) I started to use Red Hat in 1996, with the NeXT keeping its place for its graphical desktop on my personal desk. At the time I started working for a software startup where we used a mix of Linux (Red Hat) and Windows (NT) desktops, and Linux (Red Hat) mostly for servers (some Sun and BSD as well, IIRC). Around 2002(?) maybe I had mostly migrated to Linux also for my home desktop, but I kept the NeXT around for a long time, most specifically because of Diagram!, a predecessor (in spirit) to OmniGraffle.
Moving to Apple/OS X never sat right with me due to its proprietary, closed-source nature. "It works great when it works. When it doesn't, you're even more SOL than on Windows."
When Red Hat went EOL in 2004 I looked around for alternatives and most seriously tried out gentoo Linux. I love the flexibility of being able to use one distro with consistent paradigms all the way from (almost) embedded through various server configurations to a fully multimedia capable desktop. I haven't looked back since, typing this into LibreWolf on a KDE Plasma desktop running on gentoo.
All the while, I've also been using, supporting, and developing for Windows professionally to some degree (in addition to working for/on Linux and other more Unix-y stuff). It's such a quality of life hit compared to open source - I remember phone calls with prominent Microsoft employees over weird support cases involving DCOM permissions (or rather, bugs therein) - Microsoft's reply certainly felt quite like de Maizière's infamous "some of those answers could unsettle too many people" quote, hinting at security through obscurity.
Whereas in the Linux ecosystem, I can analyze to their root and facilitate taking care of even decidedly weird corner cases.
One thing I still miss a lot from the NeXTSTEP desktop is its concept of "services": Global utilities that could/would operate on anything (of suitable data type, e.g. text, image) that is currently selected (and show up in what today would amount to the context menu of the selection, regardless of which program it's in). In the simplest case, this could be a Wikipedia lookup of the currently selected word. But, services also had the ability to replace the selection, allowing for all manner of things like unit conversions, 'intelligent' expansion (what this could do together with ChatGPT!), at-the-fingertips OCR and so on and so forth.
