Despite years of antitrust battles, the Redmond (Wash.) giant still accounts for almost 9 out of every 10 computer operating systems. Yet analysts took note when Windows’ market share dipped below 90% in December. The Mac OS has been making slow but steady gains, partly due to the unpopularity of Microsoft’s latest operating system, Vista. Internet Explorer, another blockbuster Microsoft product, commands 70% of the Web browser market, down from 95% in early 2003. Yet industry analysts don’t think Microsoft (MSFT) has reason to panic, especially with Windows 7 and a new version of IE on the horizon.
