Though Symbian's certainly not getting as much share of the mobile discussion these days as some of its smaller competitors, it's certainly important to keep in mind that these guys have software deployed on literally hundreds of millions of devices, making this perhaps the largest-scale conversion of a closed operating system to open source in history.
