a) The 7-inch format would not be bad, if not as yet would be eliminated by the virtual control buttons a few millimeters of the screen.
Practically, it is thus more of a 6.5-inch screen usable.
b) The 16: 9 screen may be good for couch surfing for movies and games is 4: 3 better as more viewing area is available.
c) When you hold the Nexus with 1 hand, it responds poorly to the operation with 1 finger.
Only when you have the second hand and the Nexus, it works flawlessly. (Without cover and without protective film, mind you).
IT'S FRUSTRATING!
d) For me personally, a hardware Home button below the screen like it better so one who is / is positioned above the rear alone for wake-up.
e) The wide rim the top and bottom may be good for handling in landscape mode. I think he's ugly and unattractive.
After 8 months, I have the Nexus 7/2013 sold. I was still happy with it.
But no more, no less.
Now I have an iPad mini.
And I am happy!
