I'm so glad you started this thread.
I'm upgrade-eligible on October 14 on AT&T, so I really can't wait for it to be released. It seems like one hell of a nice device. Unlike previous Samsung flagships, the US version won't be crippled.
My Nexus 7 fits in my pocket, so the GN2 will fit with no trouble. I'll probably invest in a Bluetooth earpiece for the first time, to avoid any awkwardness from calling on the slab. For everything else the size is clearly an advantage, not a handicap.
