Some great replies guys. Thanks. :)
There are a few things I would like to answer. I was running Ubuntu Studio for a bit. It was fantastic in many ways. Tracktion runs great in it, and it is a good DAW. BUT, it just ain't Sonar! I'm thinking of re-educating myself in Music now that I'm retired (never got that degree), and the school I want to attend requires Cubase or Sonar. When I say I am a long time fan of Cakewalk, I bought the software (believing it was for DOS) before I had Windows. I actually bought Windows 3.1 to run Cakewalk. Cakewalk even then, rocked.
I realize this would be a tremendous task for programmers.
I think Linux's multi-platform abilities, and its transparency with open source, would make it worth it. Ports to some of the lighter weight OS's would be easy because Chrome OS, Android, Steam OS and others are all Linux variants. Linux may not rule the desktop, but I'm hoping that will change. :) Think of a portable system with Sonar embedded/installed along with you for gigs. Hmmm Cakewalk OS has a nice ring...
