The Next New Thing

I think a new media that isn't invented yet is the completing the Personal Area Network or PAN. We all have with several devices with us everyday and all of the time. Unfortunately, even if all of those devices are made from the same manufactures that run compatible software the data sharing is minimal compared to what it could be. The cloud is great for syncing devices that are connected to them Internet and bluetooth is great for devices in close proximity. I envision network that relies on both. For instance imagine a watch that relies on you smartphone for an Internet connection for the latest weather and and stock updates and text messages. It can be a standalone device or serve as a second screen for a phone. Or maybe just an input device? Someone's glasses could serve as a heads up display and smart phone would just be a CPU and portal to the Internet.
That portal could be a portal to your whole digital world, at home and work. You could get alerts to where your kids are. Who's at the door even though of half a world away. How about your car sending a message letting your family know your stuck in traffic with out you prompting it to. You can already manage a lot of systems such as your car's ignition and climate remotely, you can turn on lights and appliances from your cell phone. It's just a matter of having all of these networks talk to each other and work with each other.
Note.... This is a new media, not just a new technology. It would be highly interactive with your friends and family and change the way we interact with technology and each other.
