High-Tech Shopping Carts

neutron_p writes "A Massachusetts-based supermarket chain says it will roll out new intelligent shopping carts that promise to make food shopping much more personalized and interactive. They will let shoppers email their shopping lists to the store and check prices on the spot. Each new 'Shopping Buddy' cart mounts a wireless, touch-screen IBM computer, equipped with a laser scanner. The computer will also alert shoppers as they approach favorite items or promotions."
