I'm less interested in smartwatches, glasses, and so on than the idea of intelligent screens that all connect to the same robot brain. So you can walk over to a window, or a phone, or a tablet or a computer or a fridge, and it knows it's you and you can use the same apps & data.

There's two ways that can work. One is that you're building apps that know about every form factor and device capability and are deployed separately, in the same way that Netflix has 120 different versions of each video to match the exact screen and Internet connection you happen to have. That's completely nuts. The other way is that you're sending an app interface down the wire that automatically adjusts to the device that you're accessing it through.

The best technology for that is the web, and that's one of the reasons that getting identity on the web right is so important. Being able to open your watch ("open your watch"?) and use the exact same app that you use on your tablet, or your car, is a big deal. Of course, the interface changes and adapts based on the amount of real estate you have and what the device is capable of, but building individual support for every single new thing that comes along is not sustainable.

So I don't care so much about watches or glasses. What's much more interesting to me is that idea that I can access my stuff on anything. Whatever works for me, wherever I am. That's cool.
