I kind of did at first but that was simply due to my need to "KNOW ALL THE THINGS!!!"
Throughout the year though it's become apparent that the Baker's aren't really changing much of anything. The core of the program is X3 (an undoubtably popular and stable incarnation) and all this new stuff is exactly that... new stuff that doesn't screw with the main X3 foundation. You can use the new stuff or not use it but it's there when and if you decide you want/need to.
The only exceptions to the "it's just X3" premise would be the new Control Bar (which is super easy to figure out and WAY better) and the new PRV stuff which has seemingly remained the same since it was initially implemented (with necessary fixes). Everything else can be safely ignored unless you go out of your way to use it.
I've only updated SPlat I think 2 (maybe 3) times and am about to do so again to get at the track to track stuff. I've mostly been doing things as I have been since X3 but occasionally reach out to the new tools because they were useful for what I'm working on (for example I'm about to use Drum Replacer for the first time).
Also I find it BETTER with these monthly releases of new stuff because, due to my personal laid back update method, I get a chance to really let the possibilities sink in and see how everyone is using/liking new stuff. The monthly eZines was a great idea. I read through them (and download/store them with my manuals) to get an idea of what's up and how things apply to my work. This all makes it much easier to use these things once I actually DO something with them.
Before when it all got dumped in our laps once a year (AND with massive changes to how the core program worked) it took at least a couple months to catch up. Now once I do get around to installing the updates/using the new stuff I already know what's going on and my work isn't disrupted really at all. I just have some cool extra options.
I haven't really been nailed by any of the "bugs" or problems either because if I see a ton of people complaining about stuff here I just write off that version and wait to see what the next one brings. Looks like JP is probably a good version to snag and squat on. The only complaints I've seen were in regards to specific third party plugins that I don't use and over the top routing issues that can be avoided (and the Bakers said they're working on).
Much more protection and choice IMO with the new model I think and really no reason to be overwhelmed because nothing new seems to get in the way of old workflows (if you are already used to X3 or Sonar 2015 anyway).
There were some stumbles at first but this does all seem to have been thought out rather well and humming along quite nicely now.
Cheers.
