I have the first edition BWU too and think it is a superb keyboard. I switch out with my Logitech G510 every once in a while just for a change of pace but the BWU is my all time favorite. I'm a sucker for cool looks and backlights so these keyboards are right up my ally. Glad to see the next generation of these boards are just as good if not better.
