Yep, that's not a bad value, but $30 extra is still quite significant to us, and the smallness/lightness and battery life of the Chromebooks is hard to beat.
Touché. Though, to be fair, it's hard to "accidentally" do it, as there is a subsequent confirmation screen. The problem is one of ignorance, upon first receiving the laptop, and not knowing how to boot into an operating system. Once that's been settled, then it's perfectly safe and convenient to use.
