I still don't get Chromebooks. I don't buy the argument that the OS is so lightweight, as any savings one can get by getting rid of the legacy Windows cruft is more than offset by the resource demands of webapps. In fact, I'd argue that the most demanding apps I run on my Macbook are webapps as well.
They look like cheap laptops to me. And they are priced like cheap laptops as well, with all the pains it entails.
I get them for places like schools or environments where there is high risk of your laptop being stolen or damaged. If you lose or breaks one you can easily replace it with any random other Chromebook and be back up and running in minutes and it is basically impossible to 'break' the software on it (and if you do, resetting it is trivial).
