[HAM] 1st model to have waterfall keys???

[John Lynch]

My C3 is sitting right next to my BC and from what I can tell the keys look 
identical BUT the sides of the keys are more rounded on the C3 (it is 
subtle). The end result is that when you run your palm up the keys, the more 
rounded ones on the C3 roll off your hand smoothly and the edgier keys on 
the BC tend to hang up on your palm. I have always been led to believe that 
the other style of key is referred to as the diving board style 
(overhanging). -JL
