This is amazing. I like the Logitech mouse + kbd that I have but the Logi apps are crap. At some point (not too long ago) I had to run TWO Logi apps because the newer one didn't have support for my keyboard. Mind you, it's some MX artsy-fartsy with the volume knob, so it's not old hardware. Also the app was awful, the volume knob didn't work right away, then the volume would go up and down some 5 minutes later on its own. I'll gladly get rid of the Logi apps ASAP.
