After five years and numerous delays, customers can now get their hands on the final version of the Windows Vista operating system.Well, business customers can, at least. Though Microsoft celebrated the launch of Vista\u2014as well as Office 2007 and Exchange 2007\u2014at events across the globe Thursday, both Vista and Office 2007 won\u2019t be generally available through retail in the United States\u00a0until Jan. 30, 2007. Thursday marked the day business customers could purchase those products through Microsoft\u2019s volume licensing program. \n\n\n\n\nAnd though business customers can begin ordering Exchange 2007 Thursday, the new version of Microsoft\u2019s messaging server software won\u2019t be released to manufacturing until the end of December.Not only was Thursday\u2019s launch party for all three products a bit premature and anticlimactic after so long a wait for Vista, it could also be the last of its kind, according to industry watchers. With more software being pushed out to customers over the Web as services, launch parties for packaged software products may soon be a thing of the past, they said."This is a big launch for them, but for everyone else it\u2019s ho-hum," said James McQuivey, a professor for Boston University\u2019s College of Communication who specializes in marketing research and business management. "It\u2019s the biggest wait-and-see event of the week. Customers are going to wait and see when they need [Vista] and if they need it."These concerns aside, Microsoft Chief Executive Officer Steve Ballmer was on hand with his usual enthusiasm at the New York launch event to promote what is arguably the industry\u2019s most highly anticipated product launch of the year."It\u2019s an exciting thing to finally be here," Ballmer said. "That\u2019s all I\u2019ll say about the past." He had previously promised that Microsoft will never again have another lengthy gap between the major releases of its client operating system. The vendor debuted Windows XP, the previous version of its client OS, in October 2001."This is the biggest launch in our company\u2019s history," Ballmer said. "These are frankly the most significant releases of these two products [Vista and Office] we\u2019ve ever done."Vista was the big star of Thursday\u2019s event, though Microsoft teamed the OS launch with Office 2007 and Exchange 2007 for several reasons. One is that the company is trying to promote the technology links between the products to show how they can bring better worker productivity and cost savings to business customers in the hopes companies will purchase and deploy all three at once.Another reason for the triple product launch is that Vista has been so long coming, Microsoft felt it had to give customers a little extra incentive to be excited about it, said Sunil Misra, vice president of Getronics. The provider of managed services and consulting has been helping business customers prepare for Vista deployment."It\u2019s the love campaign," Misra said, referring to the launch of all three products together. "People have been waiting a long time for Vista."The last time Microsoft released Windows and Office together was with Windows 95. But during that time in the heyday of Windows, customers would have flocked to the new OS release even without its tie to Office. "It\u2019s not nearly as exciting as it used to be in the old days," said McQuivey. "With Windows 95 and 98, you actually had people waiting in line at [retail store] Best Buy" to purchase the OS.This certainly isn\u2019t the case now, as consumers can\u2019t purchase Vista until January. And it may not even be the case then, as consumers in addition to business customers have said they may hold off on purchasing Vista until they need a new PC. Many of those new PCs are bought during the busy holiday shopping season that is currently in progress, but since Vista is not available yet in retail outlets, it can\u2019t benefit from that rush. In lieu of that, Microsoft\u2019s hardware partners such as Hewlett-Packard and Dell are offering discount coupons for the OS if customers buy PCs that are capable of running it this holiday season.On the business side, customers will likely continue their Vista planning process throughout the end of the year and most of 2007, Misra said. Indeed, most analysts think the bulk of Vista business deployments won\u2019t happen until 2008.\n-Elizabeth Montalbano, IDG News Service (New York Bureau)(China Martens in Boston contributed to this story.)\nRelated Link:\nMicrosoft Windows Vista: The OS Has LandedCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
