A couple of months back, NF's veteran, geriatric HP laptop suffered a breathtaking four foot drop, fractured its hard disk and was declared comatose. This event led NF to buy a $250 Samsung Chromebook whose fan NF became right away, even as the old HP machine valiantly sputtered back to life with the aid of a new hard drive.
And then courtesy the ever wonderful Lifehacker, NF came to know about booting an Ubuntu distro alongside Chrome OS. It's not dual boot; you can toggle between Ubuntu and Chrome OS by pressing Ctrl+Alt+Shift+Back and Ctrl+Alt+Shift+Forward and unleash the full power of Ubuntu on your Chromebook in real time! See link here on Lifehacker and here on How-to-Geek.
It's been working like a dream. The next laptop NF ever plans to buy will be the Chromebook Pixel with a solid Ubuntu distro running alongside!
