I'm looking for an extremely quiet wireless keyboard for our client conference room that also needs to have the wireless connection encrypted. I've tried the Logitech MK520 but apparently it's too loud. We originally had the HP Wireless Elite v2 Desktop which was quiet enough but the wireless wasn't encrypted and the keyboard would lose connection to the PC at times (only 10 ft away from the PC). Any suggestions?
I don't think management would like a laser projected keyboard either.
