Not sure if this was changed on later revisions, but 

(1) yes, the keyboard is awfully loud; people reported to me how they 
fixed that using various methods (pieces of felt, hot glue) to dampen 
that clickety-clack

(2) the response is somewhat awkward; it takes some time to switch from 
attack to pressure detection, so unlike e.g. common channel-pressure 
keyboard you can't do a "hit-and-bend" (I like to use pressure for 
pitch-bend a second up) but rather a "hit-wait-and-bend". It's also not 
as nicely responding as e.g. the SY77's keyboard in terms of 
"linearity" over the entire pressure range.

Both my SQ80s show that behavior; I once heard that later revisions used 
within the EPS and VFX at least got (1) fixed a bit.
