I never left, actually! I just got more into Studio One after the initial "Cakewalk going away" shock. I had access to the Studio One 4 beta, and could see that it was going in a very different direction compared to CbB that was ideal for some types of projects. So I still choose CbB, SO4, or Live based on the project at hand...just like before. The main difference is now I can do a wider range of projects more easily.
For example, right now, I'm recording narration in CbB...it's still better than any other program I've used for that particular application. Then again, I also have more than one guitar and more than one keyboard
