Text Messages on Shopping Carts

I recently read on Springwise about a company called Modstream that delivers digital messages right to the handle of a shopping cart.

Modstream_2 My immediate reaction was that it's a great idea.  Then I realized I spend as much time grocery shopping as I do thinking about complex calculus.  So I asked my wife - a focus group of one.  Her reaction: "It's hard enough trying to find what you need on the shelf AND dealing with Henry in the cart.  I don't see what good it would do me."

Oh well.  What the hell do I know?
