I never owned an Apple ][, but I did own an Apple ///. And yeah, the numbering really was like that.
I didn’t immediately take to the Mac. It was different in weird ways, and I was mostly working on CP/M systems at the time.
In January 1985, the year after the Mac was released, I went in to look at buying a DOS system for work-related reasons, and I had to wait almost an hour for a sales guy. I decided I was going to amuse myself with the store’s Macintosh.
One of the things I’d had to do in the past was engineering drawings (of things like circuit boards). On DOS. (Edit: not just DOS. One of the apps we used was actually on the Apple ///, now that I think about it.) Without square pixels.
Ten minutes with MacPaint and I was sold. Square pixels! How revolutionary. I walked out of the store without the Mac, but with the resolution that I was going to have to figure out how to buy one. Not much later, I bought a used Mac+.
Since then, I’ve never owned a DOS machine — or a Windows machine. I’ve owned a few Linux devices, including some weird ones (like a Corel Netwinder), but basically I’ve been a MacOS person at all other points in the last 30 years.
