I'm loving X2. It has so many usability features over X1. I've already remixed 4 of my projects and can't wait to do more. R-mix is phenomenal. X1 was a huge learning curve, but now X2 finishes the job. Last night I was up till the early hours working to perfect an older project. I haven't done that in a long time. I'm digging it. 

I'm in full agreement regarding the step forward Sonar X2 is. In many ways, the fact that CW went for usability and finesse over bling is a sign of maturity and leadership from the product managers and bakers.
 
But what really blows my mind is that I got months and months of additional intellectual property, blood sweat and tears, many hours of time from the beta testers and a few extra "toys" - all for $99.
