Nokia N900
Symbian has traditionally been Nokia's OS of choice but with an open source version still in the pipeline, the Mighty Finn has yet to make a big impact in the open source smartphone world.
However it does have a finger in another open source pie with a Linux-based OS called Maemo, which it's used on its line of internet tablets. The latest of which - the N900 (pictured above) - comes with wi-fi and cellular connectivity, making it a smartphone in all but name.
