There are a few people in my office (web dev shop) that have Chromebooks. With a little tinkering to open them up, they're perfect.

I mean really, 99% of the time all you need is a web browser and a connection to remote into the machine that's doing the real lifting for you.

My favourite part is the disposability. If it gets trashed or stolen, all I have to do is sign in to a new chromebook and generate new keys to be back up and running.
