On the edu side, Chromebooks in schools also have the advantage of much easier and cheaper central management. This plays a big part in deployment in elementary schools, in addition to the cheaper unit pricing.
That being said, on average the kids hate them.

Well, hate is a strong word, but they definitely don't prefer them overall. At least around here at least, every single one of the kids would not choose a Chromebook for their own home machine. It's always a Windows machine or a Mac.
Some schools get iPads but Chromebooks still are the most popular with the elementary schools. In high schools though, I've seen Macs much more commonly than in the elementary schools though, especially when the schools have dedicated multimedia labs.
