Im a big guy and I had no issues with the keyboard to be honest. I say nano but its actually probally a tad bigger but still smaller than the 7100. The joystick is in the center of the device above the keyboard. on the home screen they have a place to add your most favorite six ppls picture and you can dial them from the home screen. i just couldnt get over how clear the screen was even in the 102 degree sunshine. I am supposed to get a beta unit in september so we will certainly see.
