I have to say, the three main things that blew me away after watching all 3.4 hours of the Google I/O Keynote are:
1. Google Now - I am amazed at how fast they are pushing the envelope on the voice communication with device software technology. We are probably (at most) a decade away from "Iron Man's Jarvis" level voice interaction with computers.
2. Google Maps - It's incredible how far Google has come in developing the new Google Maps and the direction they are taking it in the near future. This technology helps remind us that we are not a giant world of multiple nations. We are a tiny world of one human race, and we will only win this race if we stick together.
3. This leads into my third favorite thing of the keynote this year. I really enjoyed listening to Larry Page's speech and Q&A session (despite his voice chord paralysis issue). I feel he really gave us a sense of scale and scope for the vision that Google holds for the world. Google isn't just some company making a product. It's obvious to me now that they intend nothing less than making the world a better place with a positive attitude and collaborative efforts. He admitted they come up short, but the point is they are striving toward something greater and know that technology will help us get there.
As a sidenote, from a more mundane business perspective, I was impressed with the new Music service "All Access" and the Google Gaming Service for the Play Store. The Gaming service will help develop the Android and Google ecosystem even faster, and the Music service was a nice surprise because Google succeeded where Apple failed. From the intel we have been able to glean, the reason why Google was able to get the lucrative deal with the music companies was because they weren't greedy about asking for too much money.
Overall, these software advances were far more impressive to me than any shiny doo-dad which would simply be obsolete in six months. Okay... but I have to admit, the SGS4 GE is pretty darn kewl!
