@pdcawley@mendeddrum.org and I do! Well, a USB switch for bouncing between work and personal machine. But it has a noticeable pause when switching, so I have a second keyboard for when I'm mid-sentence in work stuff and want to toot or something. And in the evening I get silly and have both on the personal system. Primary types better, secondary has better media controls. And very occasionally I get confused, start typing on one, and finish typing on the other.
