There was also a presentation by aha mobile, they make an iphone car traffic app which is very impressive until you think about it - it is mostly visual. While there is some audio content, you have to look at the phone to get to it, not a good idea at 65mph.
The final presenter is a self-proclaimed nerd who has, as a hobby, built some very cool apps which used Google Server and open source, and while the stuff he did is programmer's programmer level, his talk was easy to follow, and his examples, while not meant to be pretty, were great.
One of the attendees announced her company is hiring, so I gave her my card. They probably don't have anything for a non-programmer, but it's an interesting business at the heart of GPS application building. Almost as much fun for me as video. Almost.
