Motorola Google Smartphone A 'Game Changer'

If it is software that makes this phone special, why couldn't it be duplicated on another Android phone? Unless I'm missing something, the hardware shouldn't make much of a difference if the goal is to tie together Google services in a unique way.

EDIT: one thing that came to mind would be a physical +1 button that could be used to +1 anything, from a picture in your gallery, to a web page you're viewing, to a restaurant where you're currently located.
