i like my operating systems to work and not get in the way of work. debian on pyra will "just work"™ in about "two months"™. that said, it is fun to install a new distro every once in a while for that new car smell.
I've talked to lord-of-all-devuan-on-arm, paralyzd (Ivan J.) and he seems quite keen to build devuan for it. When Pyra gets close to production, I would like to get 10 people to donate 70 euro in Dragonbox vouchers toward sending him a unit (or 20 people donating 35 euro, or some mix of the two).
