I agree with you wholeheartedly on the halo effect point. Without Logic and Final Cut, there’s no reason to not run Protools and Adobe Suite on a cheaper PC workstation.
I’m curious about your statement that professional-grade audio software had historically been a Mac-only affair. Is that really true? I was using some pretty serious audio production software in Windows as early as 2003. What kinds of software were Mac-only at that point?
