No, I am "That Guy"! (standing up and channeling the ending of Spartacus). I do what you do with a teeny clipboard for the exact same reasons. I also have a small card for the yoke that I have used in some form since day one. It doesn't save much time in preflight anymore vs. simply opening the flight plan, but old habits die hard. Even so, having key info such as Ramp/Metering/Ground/Tower freq immediately handy helps keep my head up during taxi vs. swiping around Jepp. To each his own.
