@lqlarry My primary laptop has a Ubuntu key, as did the one I had before it from.tbe same company (it was sold with Ubuntu pre-installed - and at the time, I was a big fan of Ubuntu and that key in fact helped sway me to that laptop).
When I got my Unicomp Model M, I also got the Linux key kit for it. Spending that much money to get my dream keyboard, $15 more didn't seem like a big deal.
(Though I am pissed Windows is the default)
