I've been wondering about this for a while, but does anyone think the physical home button on the Galaxy S3 and Galaxy Note II have anything to do with their success? The just recently released Galaxy Note 8 also has a physical home button (which was not on the Galaxy Note 10) and it make me think that Samsung feels that that button does make a difference.
Does it help iPhone users transition to those phones? I own a Galaxy Note II and will admit that having that button does make me think it's easier to use. I own another Android phone and a Tab 2 that doesn't have physical buttons, but I think there is some mental process that prefers the tactile feedback an actual button provides.
Maybe Apple should have copyrighted the physical home button. Heh.
