Noteworthy quotes form the article

"Despite the positive reviews, most analysts say Windows 7 alone is not enough to jumpstart lackluster PC sales. They cite customer animosity toward Microsoft, a change in consumer trends and the typically slow pace of businesses' OS integration as reasons."

"Windows is by far the most-used PC operating system. Last year, 83% of new PCs sold had Windows built in."

"Windows 7 may be a shiny and new version of the world's No. 1 OS, but analysts wonder if customers are willing to give Microsoft a second chance after Vista. Users complain that Vista is sluggish, has too many versions and is susceptible to bugs."

Survey data quote

"According to a survey of more than 1,000 IT professionals nationwide conducted in March by Dimension Research, 50% said they were considering leaving Windows altogether rather than switch to Windows 7. Apple's Mac OS X was the system they are most likely to switch to."

Commentary
These IT professionals would have to make the switch to Apple Macintosh computers, the only computers licensed to run the Mac OS X operating system.  Many organizations have already embraced Macs in the enterprise.  See the following article about the use of Macs at Cisco.  Apple's upcoming Mac OS X Snow Leopard includes out of the box support for Microsoft Exchange Server 2007 thereby making it easier for organizations to integrate Macs into their existing IT deployments.  I expect that many more organizations will embrace the Mac over the next few years as a result of the included Exchange support and growing use of the iPhone as an enterprise tool.  Apple is on the cusp of a major growth phase in the enterprise.
