Very cool. I was expecting to learn about the ins and outs of ink, printheads etc but instead learned "How to build a paper that acts like a printer" which turned out much more entertaining.
I've made the switch before. At first yes of course you do stare at the dash in front of the wheel for a sec before remembering it's to the side but I didn't find the learning curve too difficult. After a month or so it's second nature.
