I handled one at Best Buy just out of sheer curiosity.
It is indeed very light and small, however my biggest problem with it is that the hand grip is vritually non existent. It is actually quite difficult to hold the camera with one hand because of the lack of an indentation around the hand grip. It is quite ironic and unfortunate because since they made this thing so small, they sacrificed giving you a grip to actually hold onto.
I honestly could not imagine shooting with it. You almost need 2 hands on it at all times. What's the point of being so small and light if you can't handle it?
Go here and then click on the top view photo of each camera, and see what I mean about the lack of a hand grip:
