>Are you really using it for professional work or have seen anyone use it?
Checking in. My side-gig and paid hobby is live production, and Reaper has more than earned it's place in my toolbelt. I've recorded shows produced for sxsw showcases (not to mention two years touring as a FOH guy, and producing for a major political event on the east coast-guess what? I used Reaper for all of them) and made master mixes that ended up on CD's sold by national, headlining bands with Reaper.
I think you are horrendously mischaracterizing and underestimating the tool-and from reading your other comments to people providing you with substantial and verifiable feedback as to the capabilities of the software, extensibility, platform support, feature sets compared to more expensive DAWs, it appears you're doing so deliberately.
