In the course of learning to use QML, I have tried to build a book animation with QML for MeeGo. It not only runs well on the N900 with Maemo5, but also on the WeTab, the Lenovo IdeaPad S10-3t with MeeGo, my Ubuntu Laptop, and a friend even showed me how he was running it on Windows.
This is truly "Code less. Create more. Deploy everywhere." :)
This is a short video running a tech demo I made for the N900.
Maybe we'll see some MeeGo software with this technology one day. For now it's only a tech demo looking for an application.
