Trailing behind BlackBerry 10, Cyanogen OS, Tizen, Ubuntu Touch, and Windows Phone in the quest to challenge the Android-iOS duopoly that currently dominates the mobile market, is this little-known mobile operating system called Sailfish OS. It’s an interesting operating system that has a lot of potential, but it came dangerously close to dying off before it could meet that potential a few months ago when Jolla, its Helsinki-based developer, ran out of money and had to let half of its staff go. Fortunately, a secret group of investors has given Jolla an unspecified amount of funding to keep development of Sailfish OS going, and apparently it’s just a fraction of the investments to come.
