This is plainly an updated VX Nano - but they took out one of the best features of the Nano, the index finger back/forward buttons. Why? It makes no sense. The index finger buttons were much more comfortable to use on a tiny mouse like this, and it made it so that left- or right-handed users could enjoy the mouse. If they really wanted to add side buttons, why didn't they just keep the top buttons? Is 4 buttons really too many for a mobile mouse? This would have been the perfect travel...
