Samsung's uVending touchscreen Coke machine a huge hit at CES 2009

The lowly vending machine is due for an update, and here's Samsung's take. Judging from the huge line of people waiting for their free Cokes, these vending machines with their touchscreens, network connections, Wi-Fi, Bluetooth, and slick graphics are going to be plenty popular when they hit the streets in the U.S. Or maybe thirsty showgoers will just line up around the block for free soda no matter what — never mind the vending machine.
