I've used crouton as my main OS before. It was a while ago but I was running Ubuntu 12.10. Crouton works just fine with ChromeOS updates it doesn't break anything. Personally I ran into some performance issues as well as native hardware compatibility issues (eg you can only adjust volume in ChromeOS.)you also might not enjoy having to boot ChromeOS before you can get to your Linux environment. For making a fully functioning desktop, Gallium looks the most promising for your needs.
