The Korg I30 is a great and endearing iconic (meaning "old") arranger, Boo...isn't it steam powered?

Seriously, your post makes a lot of sense.
It certainly is the "performer" that is the bottom line...I have seen fine jazz pianists performing on digital pianos that were old technology, and far from top of the line(probably because they couldn't afford better) yet, their music was always something that drew you in, and the piano's sound was totally secondary.
