I ordered 1.
I've used the previous DK9008 cherry mx brown model before so the features will be about the same, exception that it also has USB NKRO, so i can just plug and play :} The spacebar for Cherry mx brown model sports a Cherry mx clear. Oh and it uses SMD instead of the DIP diodes for nkro; and the PCB is of slightly better quality.
Other mentions about it being more heavier/sturdy; and supposedly types quieter on brown compared to the previous model.
