Who wouldn't want a shopping cart to follow you around and tell you when you're done with your list??
Oh, people who think that it's unnecessary?
Pretty much everyone? Ha!
Check out this video of a Kinect powered shopping cart from Whole Foods. It lets you scan and complete you check out there while it follows you around the store.
It totally doesn't show what it'd be like with the other 200 people in the store, with Kinect powered carts. Sounds like a cluster of terrible to us.
Still, pretty neat in concept!
