Build quality:
Very good quality in my opinion, this remains plastic for the money of course, but the device is durable and it shows. The touchpad is very pleasant to the touch and use. The screen is a bit dark but widely visible, to avoid any time if you spend time in the sun. The speakers are good and do not sizzle. The touch screen and responsive and enjoyable to use.
Form:
The screen is 11.6 inches and the camera is a little bigger than chromebook samsung but I will not say insofar as it is too large or heavy. I like this format both compact and not too fragile.
Performance:
Like all Chromebook, it starts quickly and off quickly. No complaints about basic use, it is very fast in all expected from this type of laptop tasks. The 2GB of RAM are enough to use a little above normal. I'm not crazy tabs but I can turn G +, Facebook, Gmail, Youtube and a video Hangout together without a hitch. He turns all Chrome OS games like Age of Sand Racing or Ascend. 4gb are more comfortable if you plan to have more than 20 open or run Linux tabs above, otherwise 2gb can largely be enough for most users.
In general I recommend this Chromebook much, I am very satisfied and it's a real pleasure to use. The touch experience is still improving on Chrome OS, but it's a little more pleasant. As against this sacrifices a little battery life (between 6 and 8 hours on average).
