This is a great point. In the Project Glass video all of the products are Google's. Imagine if, instead of a product, the Google glasses were an open platform for AR like Android is for smartphones. If this were so, Google could create a new app store for AR applications, a new distribution platform for web searches, AR open web apps, and (maybe) a first-person version of YouTube (reality TV 3.0). This platform would mobilize the development community and deter some companies from building apps for the iPhone (if delivery on the Google Glass platform would be more convenient).

As a developer who is working on a product that's very well suited to take advantage of this product I'm very ashamed of Google's lack of third-party developer involvement and business vision. Sure the product looks great, but is not solely about products; it's about people, about delivering value for customers the world over. And the full value of this product would only be realized if Google takes a platform approach, opens up the ecosystem and lets everybody in (including, and, especially Facebook).

Summary of the good things I saw in the demo:

- Very clean user interface

- Nice hardware design

- Interesting functionalities

- Nice integration with Google products

- Slick animations

- Seems to be pretty fast

Initial concerns:

- Video calls in version one? What about battery life? Sometimes is better to keep some things out on first iterations

- No hints to integrations with other platforms

- Too much use of voice (we all know the state of the art in voice recognition and how long voice processing currently takes)

- I didn't see a single Web search in the video... how come?

All and all this is a VERY promising product and a very important one for the whole industry. I hope Google opens up this platform so that it can reach all the momentum and followers it deserves.
