Osteen agrees that Vista's search and security features exceed XP's, adding that he believes Microsoft's response times to new security threats in Vista are the best in the industry.

The City of Miami's switch to Vista coincides with its move from a mainframe environment to a Windows Server environment and also a move to a centralized storage infrastructure, he says. Vista's data backup features can do automatic incremental data replication much better than XP, Osteen says. "The replication model of XP was causing bottlenecks," he added.

Osteen expects to save $80,000 in power savings through the use of Vista's GPOs (group policy objects), which enable quick transitions between a computer's active and sleeping states. "Windows Vista has improved sleep mode; with XP, we were always turning computers on, wasting energy and money," he says.

Vista Not Perfect, But We Can't Wait Two Years

Noles and Osteen are not immune to the negative perceptions about Windows Vista. But both attribute most of the negativity to lack of education and testing by users.

With any operating system, Noles says, there are good items and bad items, and the key for businesses is to do complete testing to see if an OS is a good match.

"When we participated in the Vista beta program we tested the operating system in all areas of our business," Noles says. "We were not listening to the press, but testing to make up our own minds whether we wanted to move forward with it. From testing we determined that Vista would be effective in our environment."

Not that Vista has been perfect for either Noles or Osteen. Both have had driver compatibility problems and are disappointed in how long it has taken third-party vendors to release software and hardware that works effectively with Vista.

But Osteen notes that he has seen reliability and compatibility improvements since the release of Vista Service Pack 1 last February.

Did either of them consider skipping Vista and waiting for its successor, Windows 7?

A company can always wait for the next generation, Noles says, but in the end it will still have to change.

"Windows Vista is a complete architecture change, so migrating to it earlier will allow us to go to Windows 7 more effectively," he says. "We will have some of the growing pains out of the way."

Osteen adds: "Windows 7 seems like a service pack for Vista with a different interface. Plus, we're on a tight timeframe. We can't wait two years for Windows 7."
