It's running ChromeOS with the Linux dev system installed. I did last year's Advent of Code in Clojure on this device, including some airplane trips. (I didn't solve every puzzle, but the limitation on the ones I didn't get was me, not the Chromebook. It runs Emacs, cider, and the Clojure REPL just fine.)

I'm typing on it right now and it's fine for casual use. (It gets a fair amount of weekend use because I neither want to undock my work laptop nor carry around something that large, expensive, and heavy.)

Would I run it as my only computer if $500 wouldn't pressure my family finances? Probably not. If my choice was between this and nothing, that's an even easier choice.
