Recently bought a Chromebook. Quite good hardware at a reasonable price. You can get rid of the chrome os and install linux. Two options:

  1. Install the full Ubuntu. Require an external SD card. Independent OS, you do what you want with your hardware. Some configuration stuff might be painful. http://www.whatthetech.info/installing-ubuntu-13-04-samsung-chromebook/
  2. Chroot over the chrome os. Also, no clue about what the linux-patched chrome kernel do in your back. Simple, easy, convenient to use. http://www.howtogeek.com/162120/how-to-install-ubuntu-linux-on-your-chromebook-with-crouton/
