BARCELONA—Add yet another software platform to the mix. But this time, two are being combined into one, and Nokia and Intel are doing the combo.

The two companies held a press conference Monday to announce the merger of Maemo and Moblin to create MeeGo, a Linux-based software platform designed to work across a range of hardware architectures and devices, including netbooks, mobile computers, tablets, media phones, connected TVs and in-vehicle infotainment systems.

The first release of MeeGo is expected in the second quarter of 2010 and the first MeeGo-based devices are expected to be launched later this year.

The MeeGo platform will be open and hosted by the Linux Foundation. The companies expect MeeGo will be adopted by a range of device manufacturers, network operators, semiconductor companies, software vendors and developers.

Developers will be able to use Qt to develop applications for a variety of devices and platforms and market them through Nokia’s Ovi Store and Intel’s AppUp Center.

The merger of the two platforms follows the announcement last June of the companies’ collaboration.
