The sky is falling... (jk)
So much of what we do is based around computers/devices.
I view it like a utility (gas, water, etc).
I just don't see the big deal whether you pay all-at-once... or whether it's a small monthly fee.
Either way, my machines/devices have to be kept reasonably up-to-date.
For what we do, Linux is not a complete/viable substitute.
Fewer audio interface choices, lack of top quality virtual instruments/plugins, etc...
IMO, If you're not a fairly tech-savvy user, Linux is not for you. Lots of small issues can be road-blocks...
Twenty years of Windows DAW software development/refinement...
It was exciting going thru it the first time.

There's so much we take for granted...
ie: Native Instruments (new) Komplete Kontrol series of MIDI controllers integrated with their Komplete software
It took all these years to (finally) have virtual-instrument controller/software that offers workflow similar to using a hardware workstation. It's such a simple idea... but it would take thousands upon thousands of man hours to see this type of development fully realized under Linux.
Windows may not be the prettiest girl at the dance.
But once you consider all the facets... she's a keeper.
To the forum ladies, I apologize in advance for the poor analogy.
