The launch calls into question Nokia's commitment to the Symbian software

The world's largest chip maker and the world's largest mobile phone maker have merged operating systems to create a single platform for mobiles.
The new MeeGo platform, unveiled at the Mobile World Congress in Barcelona, will be used to power phones, netbooks, TVs and in-car entertainment systems.
The open-source software has been created by merging elements of Intel's Moblin and Nokia's Maemo software.
The two firms first announced their intention to collaborate in June 2009.
Ian Fogg, an analyst at Forrester Research, said that the merger was a "bold play" and placed MeeGo into a "competitive position with Android, iPhone OS, Google's Chrome and even desktop software like Ubuntu".
The technology heavyweights said that the software would run on "multiple processor architectures", meaning that it will not be confined to devices just containing Intel chips.
The mobile industry tends to favour chips from UK firm Arm, rather than Intel.
Symbiosis?
The launch of Meego calls into question Nokia's commitment to the Symbian platform, the world's most popular smart phone operating system which the firm bought in 2008.
Symbian has shipped in more than 330m mobile phones, including popular phones such as the N97.
The Symbian Foundation - of which Nokia is a part - announced earlier in February that it would make all of the platform's source code open source, effectively giving away billions of dollars of code.
The foundation launched the first open-source release, dubbed Symbian^3, at the Mobile World Congress on Monday.
At the Meego launch, Nokia's executive vice president of devices, Kai Oistamo, said that the two operating systems would co-exist, although Meego would likely be used for premium devices.
The new software will be given away for free but Nokia will make money by selling other products, such as applications. Some applications developed for Meego will also run on Symbian phones and other devices.
The first version of the software will ship in the second quarter of 2010.
Mobile World Congress runs from 15-18 February.
