I have a chromebook for traveling and light web dev work since years .. and it works, because I rooted it and allmost do not have to use the UI(I need the terminal and chrome dev tools). In general it got better, but is still horrible inefficient and not ergonomic. Or did you mean it looks good? Well, maybe, but for me a elegant UI means it does not get into my workflow and can do quickly what I want. Which .. it nativly cannot.
