This is another step taken by Apple to dominate the tablet market. I've already said that textbooks are going to be gone in 5 years or less, and it will be a huge war between Amazon and apple over that, but the market for putting tablets in vehicles, and other modes of transportation is huge.
I predict that you are going to see more and more tablets put in use in logistics and sales functions for mobile sales and shipping/delivery of goods. You won't be signing manifests and packing slips anymore, you'll be signing a digital tablet screen and wireless transmitting it for instant payment.
