The Chromebooks replaced a bunch of Ubuntu-powered machines, and they are significantly inferior in all and every aspects, unless you're using Crouton or Gallium. File management is abysmal, and the OS is overall pretty buggy, in the last week I've met: impossible to clear browsing history, Chromecast extension keeps disappearing between reboots, problems with volume or brightness settings, Wifi woes...

Chrome OS feels really unpolished and a bit forgotten.
