Intel-backed Tizen OS for smartphones, tablets and everything else has released an early preview version of its source code and SDK for developers. While there are no Tizen running devices available, yet, and the preview release is meant to get feedback from developers about what more needs to be done to ensure they develop apps for this new platform. Samsung is speculated to back this venture and is looking at merging Bada with Tizen, though a final call is yet to be taken. Intel had to launch Tizen after Nokia shafted MeeGo in favor of Windows Phone as its primary smartphone platform. Intel has been trying hard for its own mobile platform for many years now but its initiatives have not been successful, yet. It is also working with LG, Motorola and others for Android tablets and smartphones running on its Medfield platform. Developers interested in checking out Tizen can go here for more details.
