Initially, I went for an 11 inch but it remains very compact high end. A beautiful object is very well finished.
About ChromeOS, confusing at first but you get done quickly. Everything is done by the browser chrome, I'm aware of, to use, it's still unsettling. There still means that the 'links' are displayed in separate windows without address bar, and visually it looks like a typical window of a program.
Rotating with MacOS and Android at home, I wanted at all costs to avoid Windows and its burdensome on a small portable booster. And being familiar with Google services, choosing a chromebook came naturally after, however, be quite hesitant with a hybrid tablet (Asus Transformer Pad TF103 with a screen of lower quality and no HDMI out) but I really regret my choice.
