0.2"? I can humilate you so bad that it is not even worth it. Im just going to comment on why you are wrong.
The buttons are 0.2" but they just float in the air right? No, they are in a case which guess what; also takes up space.
Please think before posting
BTW, Im completely against big screen phones.
What in the hell are you talking about? As I mentioned, we are talking about the difference between large 4.5", 4.7" and 5"+ phones and small phones like iPhones pre-iPhone 5 phones, around 3.5", not the minuscule difference in having buttons or not. Secondly, as I already said, the Galaxy Nexus is the only phone that doesn't have these buttons, so by all means, please humiliate me with your superior knowledge.
