And here's another kick in the teeth. I was just looking at the Note 4. For all the complaints about the capacitative v on-screen buttons, you lose about 1/3 inch VERTICAL with on-screen. Meaning that though the N6 has the larger screen, it is essentially equal to the screen on the Note (which measures almost exactly 1/3 inch smaller on the diagonal).. Might even be smaller.
Yeah but you don't lose that real estate during important things like watching a video/movie... They go away... that small area of virtual buttons while surfing the internet, reading or on Twitter/Facebook/Google+ isn't important (then again not like 1/3 of an inch is a ton of extra video watching space either)
I think physical home, cap buttons or virtual on screen buttons is just a form of taste... My personal taste is to have the virtual buttons that go away in applications you don't want to see them (Hulu, Netflix, Youtube or any video based service) or any time you go full screen on an image and come back when I need them....
