Yeah I'm still adjust ing from the 4" to 5" screen but that's not too hard. One thing I like is being able to holster the device and not having to dedicate a pocket for it. I can't imagine holstering a note.
My first impression of the S4 was that it really don't feel that cheap. The metal bezel feels nice and the back was pretty tight so it didn't feel flimsy. Right now I have an Incipio Feather Lite on it and it feels pretty good.
