We can think of worse things to do than spend a day at a BMW dealership configuring the vehicle of our choice. To make the experience of selecting the Ultimate Driving Machine even more engaging, BMW and Microsoft have teamed up on futuristic touchscreen tech. BMW's Product Navigator is like the iPhone, only supersized and on steroids, and it proves that the inventive types at Microsoft are alive and well. Hit the jump to view BMW's new Product Navigator in action. The tabletop touchscreen interface enables users to pick a BMW, modify colors and content, and even save the finished project to a thumb drive to take home with them. As customers configure their vehicle on the Product Navigator, a plasma TV on the wall displays video and specs of that exact vehicle. Neat.
