It seems chromebooks are usable. While i don't own one, i have used Lenovo N22 and Toshiba Chromebook. Especially the Toshiba seemed totally usable, i used it for a couple of hours with no eye strain. It also had an amazing display.
Also, it seems Nexus 5X is usable. I don't own it but i need to switch to a new smartphone and i was considering the Nexus, so i tested for some time a friend's device.
It would be great if there are people in the forum that have owned and used the above devices to share their experience.
