This video demonstrates... well, not a whole lot really, except that in the event of a vacuum system failure in IMC I could depend on the CopterControl to keep my airplane "sunny-side up". Which is already worth something.
Unfortunately, airplane instrument panels being what they are there simply wasn't space to put the netbook anywhere else but on the seat. It made it very hard to check that the CC was always impeccable in its estimation of attitude, but it certainly seemed that way.
A second "unfortunately" was that the preflight calculations showed a one hour fuel reserve at the end of a 6 hour flight, which any pilot knows is really stretching things as many unforeseen events can occur along the way, which would make you eat into those last 60 minutes. The upshot was that I was unable to perform much in the way of turns and unusual attitudes because it wasn't wise to use the time that way.
A future flight might use a Nook with the new Android-based OpenPilot GCS, but no promises...
