no problem.  Just wanted to make sure I was in the demographic of those chiming in.  In my opinion, it seems more stable.  I have plugins that work that did not before.  The ARIA integration is amazing and very smooth, especially considering major integration changes tend to be very buggy initially.   Like Mystic, I thought the Nomad Factory plugins were just fluff but I find myself using them more and more.  The color enhancements were something  I did not care about..until i actually used it.  Big help on those large projects with lots of busses.  There are things that.  If you absolutely hated X2, i doubt this will convert you since much of the change is under the hood.  The bug fix list is lengthy but if those were not your particular issues, they are not likely to impress.  For me, I find sometimes issues that are not specifically listed have a way of clearing up issues that do concern me. Addictive drums is a major upgrade over Session Drummer 3 but i am glad they kept SD3 since it still can do a few things AD can't.  Overall i am very pleasded and sincerely think X3 is the best version of Sonar yet.  Still hoping the next patch addresses some issues they promised were coming , but for me they are minor things in the "would be nice to have category".

From my perspective, I don't really respect the way X2 was left alone and X3 was brought in

I think that is a gripe with many users who haven't upgraded (including me)..  certain products I use by rivals really don't have as much after release "snagging" that needs bug fixing.. I really do hope cakewalk improve on that front.. if they are so keen to charge a yearly sub , so quickly.. marketing or not.. "new enhancements" (yet also some bug fixing)
 
 

SONAR X3 is awesome!! Oh wait, you probably don't want to hear from me :)

FWIW, I didn't have much in the way of problems with X2. I am definitely happy with X3. 
 
I expect there to be be an occasional glitch here and there - it's the nature of a real-time system wherein you don't control the OS. Naturally, this usually occurs with plug-ins, you don't control them internally, (as you likely didn't write them either..)
 
You can do a lot in an application to prevent things such as deadlocks and and add smart behavior to handle situations such as missing resources - but only so much. You can build an impregnable system, and it will likely be completely unusable. (Sorta like the direction of Homeland Security in the US, no? )
