Measuring Linux maturity by chromebooks is silly though. It's a hack. Linux on bare metal works really well these days. Especially if you use a machine that has linux in mind (ie dell xps).
I briefly tried switching to Ubuntu on my desktop a few months ago after being unable to compile some CUDA project on Windows. Gave up after spending several hours trying to figure out why it refused to set one of my monitors to anything other than 1024x768. Linux is easily the best operating system for productivity, but there are still too many issues to make it as comfortable as OSX or Windows for everyday use.
