ARM Chromebooks have been a thing for almost a decade now. They ship with Chrome OS but it's usually fairly easy to install a more standard linux distro on them.

It's a Chromebook/Android Tablet hybrid for $300. It's now my primary ereader and "laptop" when I'm away from home since it has decent Android and Linux support.
Chromebooks keep being overpriced for what they offer.
