WSJ.com - Microsoft Move Into Cellphones Worries Some in Telecom: "At first blush, Microsoft Corp. doesn't appear to be much of a threat in the market for software to control cellphones.
Most of the 500 million handsets sold each year still rely primarily on software written in-house by cellphone makers. Microsoft supplies operating software only for so-called smart phones that can play videos and double as personal organizers. And even in this segment, it lags far behind Symbian Ltd., a London consortium formed by No. 1 cellphone maker Nokia Corp. and other cellphone companies to keep Microsoft at bay.
But after a decade of trying, Microsoft appears to be gaining some critical traction in wireless communications, especially as cellphones increasingly are turning into minicomputers capable of surfing the Internet and sending e-mail. That is sparking concern in the software and telecommunications industry that the Redmond, Wash., titan will use its clout in the corporate e-mail market to grab a dominant position in the world's cellphone market."
