I was a little nervous to update my Air 1 to iOS11 but so far I have to say that Im pleasantly surprised at how well things are running right now. Im not a power user per se but I run a my fair share of big games and some productivity apps. So far, so good! Perofmance almost seems better in some ways versus 10.3.3. Is this just me being naive or have other Air 1 oners found their device to run as good or better with iOS11? Of course, I still want a 10.5" iPad Pro as an upgrade but this at least allows me to hold off for a *little* longer.
