Thanks for your comments, Chasfield.
Interesting view on the keyboard operation!
The 57 gives a mechanical feedback as long as a strong force is used when pressing the keys (is this the reason why people says Texas is on the "dark" force? ) while the Casio's are absolutely feedback less and way to smooth requiring near zero force applied.

I guess HP was in the sweet spot taking the green spectrum region with their magnificent Classic series.
