Not really; my previous job was maintaining a commercial Linux-based desktop. For that one I had a powerful local machine so I could run some desktops in virtualization; I hardly wanted to use my own machine as a guinea pig, because I needed that machine for actually getting work done. I did in fact have a desktop Linux machine on my desk, but in practice I just ran shells and Firefox on it, and half the time I was connected to my screen remotely.

A CrOS-like OS with the ability to run VMs would be pretty great. (And yes, I should check out Qubes.)
