As far as the annoyances of their marketing, I can't think of but a few that haven't (yet) done something to not only annoy, but infuriate me. At this point, I still have a couple of niggles with Sonar in what use to work fine but no longer do (The most important being how they now not handle class compliant controllers and break function). But I also don't care for their new installers making you install everything when all you want is a single item in that category. Given their history, I would venture to say that the customer base making enough noise about them only implementing load balancing in SPlat will eventually get them to buckle and implement it in the full line. So those 'rants' are what I would believe to be worthy.
As far as PreSonus goes, great service response that Cakewalk could definitely learn from. However, in my dealings with PreSonus, the bottom line was they couldn't figure out how to make it work on every system with mine being one of them. At least PreSonus admitted it though and gave me a full refund, which is more than I could say for some developers.
With the current Sonar, I'm getting the most stable and easiest to work with DAW for me yet. Load balancing is definitely a winner that seems to kill many previous issues. And I don't think I've ever really had to scour the manual to figure it out either. Although I do read the forums for it regularly.
Let me add also, that the Sonar updates have finally achieved a consistency that they never had before. Every piece of software I own produces a double bind of the 50-50% of expectations in how much an update will benefit or infuriate me though, and right now, Sonar has shifted higher to the side of benefit more than annoyance. Things are definitely looking up.
(But as with all software, "Subject to change without notice.")
