Potential

Imagine a market in which you can find every single item you are looking for, through the touch / interactivity of your shopping cart.
Imagine a cart with a tom-tom GPS unit, a horn, autodrive and price checker all built-in.

Why can't a shopping cart be wirelessly connected to an instore-system ? Why can't they be fit with an LCD, or bluetoothed to your blackberry / iPhone / Android ? Imagine the data that could be collected from people's shopping experiences, helping shop owners to pinpoint the most sought after items, and keep them regularly stocked.

I think that the Brown Jug has some upgrading to do.
