Eyes only evolved ~600 million years ago (Cambrian Explosion), not billions. Just a picky evolutionary biologist chiming in. Looks awesome though, hope to see one in an upcoming Nexus.
I have devices at every screen size (3.5, 3.7, 4, 4.7, 7, 10, and 13[laptop]) and they all have their own uses. I’m not going to read comics on anything smaller than 8 and not on my laptop because that sucks. Also wont watch movies on my gnex. My ipad and htc flyer are awesome pieces of hardware and I use them every day, in places where I wouldn’t want my laptop and to do things that would be painful to do on my phones.
