Apparently Nokia is working on an Internet tablet operating system that is also phone-friendly called the Maemo Harmattan. The Maemo is expected to show up at the end of 2010. The Maemo Harmattan homescreen is a scrollable page. Widgets can be added to the operating system too. There is a scheduler, a calendar, maps, etc. The widgets are interconnected with each other. For example, an alarm can be connected to the calendar. Nokia would also make money by selling advertising widgets that can be embedded into the operating system.
