Ask Slashdot: Best Choice of Linux Laptops For Elementary School?

An anonymous reader writes "I work in the tech department of an elementary school and I am trying to show the tech director the world of Linux. I will be installing edubuntu but I am not sure which laptop to get. I know there are companies like System76 that sell laptops with Linux already installed but I wanted to ask you for your thoughts. We want something small and light weight for the kids. We do not need much horsepower as the main use will be internet/email/word processing and whatever other apps come with edubuntu. Basically, what we really want is something MacBook Air-like but not nearly as expensive. Thoughts?"
