expected benefit from the agreement between Microsoft and Nokia

From unit LiMO expect the alliance to the detriment of Symbian encourage small-sized manufacturers to seek alternative platforms

The Linux operating system has begun to gain momentum in the mobile with the rise of Google's Android system, which is now the most widely used software in smartphones.

"With Microsoft and Nokia and Android seated together, other device vendors should consider other areas to prevent the irreversible collapse of the margins were computer manufacturers," said Morgan Gillis, LiMo's director, to Reuters.

The market for software platforms on mobile was led by Nokia's Symbian operating system for a decade.

But its position has weakened since the advent in 2007 of the Apple iPhone. And last week the announcement that Nokia will use Microsoft's Windows Phone closed the cycle Symbian.

"The new partnership has enormous upside for Microsoft, although there is a significant risk that current Windows Phone vendors now feel alienated," said Gillis.

"is clearly a huge adventure for Nokia, but they were caught between a rock and a hard place, "he added.

Linux is the most popular free operating systems called open source, which allow users to use, change and share.
