OpenBSD on the Microsoft Surface Go
For some reason I like small laptops and the constraints they place on me (as long as they're still usable). I used a Dell Mini 9 for a long time back in the netbook days and was recently using an 11" MacBook Air as my primary development machine for many years. Recently Microsoft announced a smaller, cheaper version of its Surface tablets called Surface Go which piqued my interest.
Quite a few things don't yet work on OpenBSD, but these first few people who try things like OpenBSD on new Surface devices pave the way for support to improve.
