Form factors: one of my colleagues came into my office with cardboard cutouts of the new iPhone 6's and held them up against my Nexus 5 -- which turns out to be nearly identical to the iPhone 6 in size.

So, there's that at least.

Watches: I had a moment yesterday where I realized wow, I'm living in the future. I had Pandora going in the background (casting from my phone to the Chromecast gadget in my theater rack). The phone rang. I answered it but then I needed to mute the song. And there, on my LG G watch, was a pause button, because Pandora exports that into the Android notification bar, and thus it gets forwarded to the watch. One tap on the watch and the music stopped.

Think about how many distinct computers in how many different locations were involved in me pausing the flow of music to my stereo just because my phone rang.

It's the future, I tell you, the future.
