Well...I know some of them...mainly the ones that sound nice.
I do love the drum icons on my S900...I don't program drums often enough to remember them...I generally change bass lines, chords, phrases and pads when editing styles.
I don't think it makes keyboards look uncool...they are just more user friendly.
