Table: Microsoft by the Numbers

BUSINESS DIVISION
Revenues: $19.4 billion
Likely the most profitable unit in 2009, it will offer free Web versions of Word and Excel to drum up interest for Office 2010. And it's selling more of its programs as online services--trading up-front payments for monthly fees. The bet: that such "cloud"-based sales will rise more than profit margins fall.WINDOWS
Revenues: $14.6 billion
On Oct. 22, Microsoft will replace its beleaguered Vista version of Windows with Windows 7, which is winning unfamiliar raves for reliability. And to compete in a post-PC world, the new operating system is designed to work with smartphones--particularly those running the company's Windows Mobile code.SERVER SOFTWARE
Revenues: $14.2 billion
Microsoft's fastest-growing business makes the software used by companies to run their computer networks. The outlook is bright. Low-cost servers that use Windows continue to displace pricier IBM mainframes, and they hold their own against models that run on the free Linux operating system.INTERNET
Revenues: $3.1 billion
In going after Google, Microsoft has lost $3.5 billion in its Internet business over the past three years. Analysts think the Net operation will need to be subsidized by profits from the Windows and Office units for years to come, even though Microsoft's new Bing search engine is off to a strong start.ENTERTAINMENT & DEVICES
Revenues: $8.1 billion
Cell phones that use Windows Mobile software have lost ground to Apple's iPhone and Research In Motion's BlackBerry. Microsoft's Zune MP3 player continues to struggle, and its Xbox isn't the phenomenon Nintendo's Wii is. Still, improved sales of the game console have put the division into the black after years of losses.*All revenues are estimates for fiscal 2009, ended June 30, from Jefferies & Co.
