In the 90s as I was buying I actually was going to go with BeOS and had a Tascam DX2424 external hard drive recorder (Thing was awesome). Steinberg, as I was a week away from buying my first Apple computer, pulled the plug on BeOS applications. I went Windows NT Nuendo 1.0. 80% of the studios my size were all ProTools. I HATED ProTools and their hardware lock in.
After a while I kind of got a niche going and I would also work at mixing or engineering things at Apple based studios about once a month. I have always had the unfortunate luck of making every single Mac crash while I use them. I would speak about my frustration and the "Mac Guy" would shake his head and say I don't know as I would have to redo hours of work.
Later on in Video. I would be on Premier or Final Cut Pro and the same thing would happen where I was in the middle of hours long sessions and I would get some crash that wouldn't lose me work anymore but it got me out of "The Zone." If you ever did major video editing you know what that feels like. The Apple "crash" was different because sometime it would take a while to realize that while I have the video gui up what I was doing wasn't actually changing anything, or I couldn't grab a clip from a folder and import it OR the codex just isn't working so I can't see a preview and I would have to reboot.
I hate Apple software like Final Cut Pro because they use their own vocabulary. It was always not the standard vocabulary of the industry pre-digital nor what the other video/audio world was using.
Software Synths (Windows/Linux) seem to just work for me these days. My buddies swear with their Macs they can do the same things and then boom back to sampled sythns after a month or so due to "little issues" but they would never blame their machines or OS. I have noticed a ton more Windows in music performance the past year or two, but I really think that Linux could make a niche in live audio production a reality if the Native Instruments would provide a Linux port.
Non-Apple world is pretty ripe for Apple to lose massive market share like they are seeing the last 3 years in video.
