I'm not quite *that* geeky, but I did feel for a long time that Macs were unintuitive and preferred Windows.
I've been a Mac User for over 20 years now (as a Mac being my primary machine) however I started off with a ZX81 and then had a yearly or bi-annual update cycle covering likes of Sinclair Spectrum 48k, Commodore 64, Acorn Electron, BBC Micro, Commodore 128, Atari ST, Amiga ...
After the Amiga I got my first PC - which back then was assembled locally rather than pre-built. Had to learn the innards and then next machine I built myself... Eventually when I went to Art College they used Macs. I didn't find them unintuitive at all, just different. I always find the common ground and there is a lot more common ground between devices than differences (same now with iOS & android).
Since University I've basically been in Mac (starting with end of system 7, onto OS 8, OS9 then OSX) as my platform work wise and because printed media / graphic design / digital editing & video it's pretty much the platform of choice production wise.
That being said I've always kept using PC's and now living in a rural area I'm constantly fixing PC's and mostly from software issues where you have to learn everything I/O about the OS
A few years back Microsoft awarded me an MVP in Macintosh - at the time the only MVP for Mac platform in UK & Ireland. I did that role for a few years until work commitment meant I could no longer spend my free time fixing others Mac / Microsoft software issues. Likewise if I was in a wider 'geek' network - the MVP Award might have meant more work wise, as it stands in a rural county with a bunch of farmers - it's means little to your work load as no -one knows what a Mucrosoft MVP is.
So yeah my computer history clearly makes me a big geek, and the MVP award did cement that as it meant a big company recognised that I was one too and the fact my geekiness has always been so diverse probably explains why I like having multiple mobile devices with one as my base and others constantly changing around that.
OS X is my base OS computer wise, IOS for sheer integration my base mobile OS - but will constantly dabble with the other side on a daily basis on mobile and weekly via computer (as I now look after the local national schools servicing and repairing their computers and I am - not out of choice - the local go to person people turn up-to on the doorstep with a laptop or desktop out of the blue with issues on an often most irritating time basis) ... When most of my integrations with Windows is fixing stuff - it's nice to go back to MacOS for me and not have so much hassle though as Mac's have become mainstream and more common place I do get to see a few macs each year that people have messed up and O have to rectify ....
