The trouble with being constantly up to date is that updates frequently break an old trusted workflow that you depend upon, especially if it involves 3rd party extensions or plugins.
This!
I committed an error last fall and finally upgraded my OS after 3 years on the original OS I had on my machine. Because I wanted to upgrade certain plug-ins and my old OS wasn't supported.
Turns out that, despite being compatible the newer OS, there was quite a drop in performance in Logic.
Never again! I intend to keep my next machine completely out of the upgrade loop save for minor updates, even if it eventually means scarifying a few 3rd party plugs.
A subscription model would ruin that plan.
Did I mention my brother-in-law still runs Pro Tools TDM 6.x on a G4/OS9 in his commercial studio? If it ain't broke...
