I've had a chromebook (the Samsung model) for the past 4 months I've been travelling around the world. It has proved to be a practical, light (1 kg) and powerful little computer. Using crouton, I've installed lubuntu so that I can have Linux and ChromeOS running at the same time. I've been able to work coding Clojure, installed GIMP and Inkscape, watched movies and I could have installed Open Office but I didn't really seem to need it. Maybe the chromebook hasn't found a market yet, but I think it's the most practical computer I've owned. I think I would prefer a Macbook Air but the price is 4+ times the one for a Chromebook, which might well be worth it but I don't have the money for now :P.
