Like everyone else, I am very distressed by all the news about Cakewalk. My two biggest concerns, of course, are future authorization issues and Sonar getting broken by some future Windows update. Thankfully, it seems like Cakewalk will give us a way to still use Sonar if the servers get shut off, so the only remaining problem is Windows. Honestly, though, I've never seen any update of Windows suddenly "break" Sonar and then Cakewalk has to scramble to fix it. It's never happened, as far as I know.
That being said, I will probably look into Studio One in a few months. I'd like to have a cross-platform DAW since I currently run Sonar on my MacBook Pro via BootCamp. But it's going to be very difficult to transition out of Sonar since I have been using Cakewalk since I was a kid in the early 1990s. I feel like my best friend just died.
