Also coming from a 7, and yeah, it's real big. Kinda split on how I feel about it. On the one hand, it sure is nice, and the interactive gestures are surprisingly intuitive. On the other, it's tougher to use one handed, especially having small hands. I have to use reachability more, which isn't (yet) quite as easy as the double tap on home. Also there's just something about the comfortable snugness of a smaller screen, but maybe that's just me.
