my…comments about linux…more of my odd opinions…lol…
I don't really want to write too much here for fairly obvious reasons.
I'll write a quick aside relating very loosely to the Abbey Road & Martin observation ... Most, possibly all, of the cinematic CGI stuff runs on Linux. Nether Windows nor Mac were capable of that in the early days. I'm not sure they are even now.
The reasons that Windows and Mac are most popular desktop OSs is because of the power of marketing and because they're the path of least resistance.
