People who buy Chromebooks for Linux are doing it wrong
I don't get buying a Chromebook and installing another Linux distro on it.
Instead of getting a Chromebook, in particular, Acer's, simply get the Acer equivalent Acer Aspire One. I got an Acer Aspire One 725-0687 for under 200 US dollars at Walmart for a holiday sale as opposed to the roughly 200 British pounds price being quoted for the Acer Chromebook. I don't have to worry about having to install only a hacked Ubuntu 12.04: I can install ANY Linux distribution I want, in my case, Debian unstable. Everything from wireless to suspend just works in Debian.
