Okay so we know about Chromebooks, They are cheap and cheerful laptops, that work surprisingly well for their price, Although I do not own one... Yet... I follow these closely, Although I am waiting for Toshiba to do something (Any tosh product I have had has never let me or anyone I know down) They are due to release their first Chromebook very soon, Q1 I believe, I feel it is time to explain the best I can about the true power underneath these little things.
Okay, so the chances are the chromebook has an Intel Celeron/Haswell processor or a Samsung Exynos processor, which are Dual cores, 2GB RAM and 16GB SSD based storage, these specs are small, but with a little tinkering can become powerful.
First think to know Chromebooks run Linux, although you more than likely know this, They run an heavily edited version of Gentoo, so you cant use terminal and the repos, Google has full control over ChromeOS. But we are not going to use ChromeOS, we are going to use Linux.
It is recommended a bleeding edge distro is needed, Some devices in the laptop may not work such as trackpads and wireless cards, this is like dealing with a mac, just cheaper and better, So pick something like Arch, Fedora or Sabayon/Gentoo (If sabayon works), Then install coreboot, so you have a free bios that is accessible.
I wont be explaining this, But there is guides all over.
With your distro installed and working, you have just unlocked the true power of a chromebook, a laptop at £200 that can smash a lot of £400/500 laptops due to software, you may only have 16GB SSD, but one you have an SSD and two nothing wireless storage or external HDD cant solve.
Your security is also still superb, I would recommend configuring NFTables and ClamAV if you know how to do this, ClamAV can easily be installed via terminal, NFTables is built into the kernel as of 3.13.
So if you get this working, you technically have one of the best Laptop deals on the planet, Chromebooks are brilliant for linux, and you can then spend the extra £200 in your budget on stuff like external HDDs or software :)
