Thanks, George, for your great review.

You don't refer to PSR2100 keys, and its feeling. Are exactly same keys and same feeling than PSR2000? Or is it better (I would like it)?
New PSR has "live" grand piano voice. You refer a more natural sounding in the upper octaves... but, only in the upper ones? So, do you think this new voice only improve old "piano voice" in upper octaves and not globaly, all around the keyboard? Do you think this new voice will sound similar to Tyros live grand piano voice (both on similar external amplifier and loudspeakers, of course).
PSR1100 hasn't "live" grand piano voice... Is it ok?
Cheers
