But Microsoft Corp., with the deep pockets, has worked away at it and by the last year, after first launching it in the year 2002, Windows Mobile have had a respectable 13.9 percent of the worldwide smartphone market share as according to the researchers present at Canalys.

Canalys has also said that during this year, there had been an abrupt backward slide. By second quarter of the year 2009, Windows Mobile had slipped to only about 9 percent of the market share, which is its lowest since the early 2006.

The question now arises that what happened after this and also can Microsoft reverse this slide? When most agree about what has happened in nutshell, the Apple's iPhone, there have been some disagreements over what has to come. Many of the analysts are saying that the Windows Mobile is too far behind and will be fading into obscurity or the thing that Microsoft would be quitting this business. But the others are saying that mobile is too important and so Microsoft would buckle down now and would be investing in a turnaround.
