Thank you. I am now seeing red squares and blue lines in my vision
there are a few other interesting comparison. you've got 4:3 to 16:10, but also throw in 16:9. all 3 side by side you'll see there is actually quite a remarkable difference between it all.
except for movie watching, I actually prefer the 16:10 size as it gives you a little more height for productivity.
The next thign that screen shape and physical size, doesn't also necessarily represent screen real estate.
higher resolution display, even while physically smaller, provides more pixels to be able to put more on the screen. some limitations being, you need UI elements that are both usable and readable. But, even if the N7's screen is technically smaller, at the higher resolution, you can put more stuffs on it.
there are trade-offs to both. after using both 16:9 and 4:3 tablets, I do much prefer the 4:3 ones myself. but I do recognise this is a personal preference
