Where I worked in the 00s, they had rack mountable kvm. The clients were just a small box with utp and the peripherals. A double press on ctrl opened a menu and you could choose a server. Neat.

it was embedded/client land for embedded systems that were connected to tvs (had one of those on my desk too). i had a primary windows dev box for wrs tornado and e-mail and then a linux box for ci dev and build/release infra. the kvm also allowed me to switch to whatever engineering sample hw i had on my desk. fun times!
