I missed this presentation, got stuck discussing with several vendors in the exhibition area. I know all the important companies are sponsoring dotMobi, primarily to simplify the creation of mobile friendly sites and the awareness for everybody with a website what it meas to deliver the best possible user experience on a mobile phone. The best information about dotMobi is the following TypePad blog;
http://dotmobi.typepad.com/

I myself use MoFuse, they make it extremely easy to create a dotmobi website. See, http://tlidforss.mofuse.mobi

More from this event will come in newer blog posts from Thomas Lidforss International
