Even with all the touted improvements, analysts expect Vista to only gradually appear on corporate PCs, especially in big organizations where upgrading can be a costly, complicated affair. Gartner Dataquest predicts that it will be 2010 before Vista outnumbers the previous operating system, Windows XP, on business computers.
Big companies need to test internal business applications on Vista before a company can switch its PCs to the new operating system, a process that Gartner analyst Michael Silver estimates at 12 to 18 months in many cases.
In the meantime, the last operating system, Windows XP, works just fine for most companies -- especially with a security-enhancing patch known as Service Pack 2 that Microsoft released in 2004.
Kamal Anand, chief technology officer for TradeStone Software Inc., a Gloucester, Mass.-based provider of supply-chain software, examined test versions of Vista and Office and found ''no compelling need'' to upgrade his company's 100 PCs and laptops anytime soon. Instead, Anand expects Vista and Office to slowly permeate TradeStone as it buys new PCs for employees in coming years.
''Nobody wants to go through the extra time and effort and money to upgrade an existing, well-working system,'' he said.
