Microsoft's customers are putting the company under pressure to deliver Vista on time. That's according to several industry analysts who believe that the software company's delays in product launches are making some customers lose patience.
Businesses that subscribe to Software Assurance, Microsoft's programme that allows free upgrades as part of its volume licensing programmes, want to see new versions released to get value for their money, analysts say.
"The irritation for most enterprises is that they are not getting the new versions as part of their software maintenance agreement," said David Bradshaw principal analyst at Ovum Ltd.
Software Assurance also offers benefits such as telephone support, web-based support and classroom training, among others, Bradshaw said. The programme has become an increasing revenue source for Microsoft, he said.
While the number of complaints has been low, Gartner has seen a "decent" number of organisations that have dropped their Software Assurance agreements on Windows because they felt those weren't of value, said Michael Silver, a Gartner research vice president.
Microsoft has said it has not determined when it will release Vista to manufacturers, but has said it is on track for the general availability of Vista in the second half of 2006, according to a Microsoft spokeswoman. Vista's release date will be driven by the product's quality, she said.
The company has said that some Vista encryption features will only be available to customers who have Software Assurance or Enterprise Agreement coverage on their Windows client, wrote Michael Cherry, an operating system analyst with Directions on Microsoft, in his paper titled [i]A First Look at Windows Vista[/i].
Users of Windows 2000 are likely to be the first to move to Vista, as vendor application support dwindles for that OS, Silver said. Windows XP users have more time, as mainstream support from Microsoft will continue two years beyond the Vista release, which now would be 2008, said Cherry.
About 25 percent of the installed consumer OS base uses Windows 2000, Silver said. For businesses, including educational institutions and government, the figure is around 37 percent of the market, Silver said.
Organisations with Windows 2000 may opt for a total hardware and software upgrade, Silver said. Organisations using Windows XP may delay moving to Vista until they decide to buy new hardware, possibly coordinating a change with the release of Office 12, the code name for Microsoft's office suite currently in a technical beta release.
But over the next two to five years, the desktop business in the enterprise is going to undergo long-term challenges, Bradshaw said. The enormous cost of running heavy desktop clients may give way to less expensive, thin-client configurations, he said.
Windows Vista is likely to see strong competition from vendors such as SAP or Oracle offering hosted enterprise applications running within browsers, Bradshaw said. Google Inc. and Sun Microsystems are also working together on a software-as-services concept, which is another potential challenge to Microsoft's long desktop reign.
A widely-publicised memoo last month from Ray Ozzie, Microsoft's chief technology officer, emphasised the company's commitment to the software-as-services concept. But the question looms: "at what point do they begin to cannibalise their own desktop revenues" with those services, Bradshaw said.
