Amazon eschews the kind of ethereal glow-light effect seen at the Target store in favor a matter-of-factness that seems to simply boost the convenience of replenishing stuff you need all the time. Who needs a shopping list—pen-and-ink or mobile or otherwise—when you could hit a button or—in the case of the Brita pitcher and other items—let the pet food bin or water pitcher do the ordering for you?

A self-driving car being tested by Google struck a public bus on a city street, a fender-bender that appears to be the first time one of the tech company's vehicles caused an accident. The collision occurred on Valentine's Day and Google reported it to California's Department of Motor Vehicles in an accident report that the agency posted Monday. The car was rolling at 2 mph and the bus at 15 mph. No one was injured.
