Personally, I wish for an ARM notebook market coming out of the Chromebook, with different configurations for Chrome OS and Ubuntu etc.
This. I really would like a small netbook type ARM device which runs a normal Linux distribution and doesn't cheap out on battery capacity. The Samsung ARM Chromebook comes near but it could have a better display, casing and keyboard (ideally with a trackpoint).
My ideal machine looks a lot like this as well. I'm surprised someone hasn't built something in between the Pixel and the Samsung, and partnered with Canonical.
