Last week I was in San Francisco for MeeGoConf SF, the second large-scale MeeGo event. A lot has changed since the Dublin get-together last November — or at least that's how it looks from the outside. Nokia (one of the co-founders of the project) hired on a new CEO from Microsoft, who announced in February that the Finnish phone maker would start using Microsoft's Windows Phone 7 instead of its own smartphone operating systems. To a lot of mobile-phone-industry watchers, that looked like bad news for MeeGo, and it certainly disappointed a huge portion of Nokia's MeeGo and Qt engineers, not to mention Maemo fans. But there is more to the MeeGo picture, which frames those events in a different light — as last week's event showed.
