Now that I've not only seen what S1V3 offers but actually gone ahead and upgraded, I can finally say that I'm ditching Cubase and going all-in.
PreSonus know what they're doing, they've made some amazing changes, added new features, and (most importantly) maintained the approachability and stability and workflow this DAW is known (and loved) for.
I'm super-psyched and I'm just sharing the news here in case someone else is looking to switch, or looking for their first DAW.
I'm now something of an S1 evangelist/fanboy, and while I still respect & love 'em all, S1 is my new best friend, and I look forward to a long relationship with it.
