It's good for small, light, cheap machines, you just need a web browser and really good battery life. I certainly got good value from the Chromebook I got seeing as it cost so little. The idea of a Chromebox for most users seems bonkers though. For me Chrome OS is very much a secondary thing and even then, now older Windows machines are good enough, unless battery life on a low budget was really the thing I needed, I'm unlikely to bother again.
