Rich,
First and foremost think you for the excellent post.
I have used Avid in the past, started out with with FCP 3, skipped version 6, now working under X and have Resolve 12 as an option. For me Resolve has top notch color grading tools, an interface that does not look like it came from a dinosaur age and I own a Blackmagic Cinema Camera planning to add a Digital Bolex to the mix.
On top of that, Resolve is becoming a better NLE alternative though there is still room for improvement. I prefer the node based environment for color grading, just me. Now the people from Blacmagic Design Team just released Fusion for Mac OS X, also node based. I am not a high end compositor type of guy, for from it. On occasion, I like to add some style to my footage on a single scene basis. Fusion gives me the power and flexibility. Besides, nodes are fun.
I also have Motion as part of the mix for the times I need to do a quick and easy motion graphics package. It also always for me to build custom titles, generators, transitions and effects to publish out for use in Final Cut Pro X, a very nice touch. Avid lacks blend modes and other tools that often come in handy for such needs as just described. Not saying Avid is a bad tool, just does not fit my needs right now. I do like the road Avid is taking and will certainly consider them again. My two cents, which is not worth very much in this screwball economy. LOL
