However, Chromebooks supposedly come with well-tested Linux support. If this is a guarantee that the drivers will get security updates for 10 years and be mainlined into the linux kernel (and if there is a way to get these things with a normal keyboard and BIOS), then this is great news. I'd never run ChromeOS, but would happily buy a flagship-grade laptop that lived up to the expectations in the previous paragraph (and then run Linux or even BSD on it).
