Light Chromebook/Netbook for running Linux?

Thinking of buying a Chromebook, and using chroot-chronos to run Linux on it. Need a decent keyboard. Any views ? Any views on the following ? -Acer c720 -Acer Chromebook 11 -Asus c201(rockchip processor)

Acer seems to support all Linux versions perfectly. But c720 is so ugly.. :( Any views ?
