That is exactly what it is. To this day I have no idea why people use USB for keyboards. A stupid PS/2 port has n-key rollover (i.e. I can mash all of the keys with no ghosting) and does not take up my usb ports (although admittedly I have 8 not counting hubs, which is a bit excessive).
Anyway, nice keyboard. I prefer mechanical, but a good non-mechanical switch is not so bad.
