Canonical, the creators and maintainers of Ubuntu, a Linux operating system, has released details about their new phone operating system Ubuntu. Wait, what? That's right, Ubuntu will soon be coming to phone near you. The Android-based operating system is billed by Canonical as "more immersive [and] less cluttered."
They are also saying that it will be powerful enough to be used as a desktop system, though that sort of phone-as-a-PC thing didn't work out too well for Motorola. The mobile OS space is fairly crowded, with iOS and Android dominating and Microsoft trying to make Windows Phone viable, so it will be a tough battle for the fledgling operating system.
Mozilla is also working on bringing out a mobile operating system and Samsung, Intel, and others are working on the Linux-based Tizen. Smartphones using the operating system aren't expected to ship until 2014, so it will likely be even more difficult for the OS to gain traction. With that said, you miss every shot you don't take.
