Analyst group Gartner claims businesses shouldn't skip Windows Vista altogether and wait for the next version of Windows:
Gartner said companies have "significantly delayed" the start of their Windows Vista migrations, with most planning to begin deployment in late 2008 or even 2009, making some think of skipping Vista altogether.
But Gartner research vice president Michael Silver has warned that the next version of Windows, code-named "Windows 7," may also suffer from the delays that dogged Vista and be just as difficult to adopt.
"Organizations that tried to skip Windows 98, Windows 2000, and Windows XP often had ISV (independent software vendor) support issues, and a difficult and rushed or forced migration. Organizations that try to skip Windows Vista are likely to undergo the same perils," the Gartner research warned.
For example, while Microsoft will support business versions of Windows for at least 10 years, and Windows XP is expected to be supported with security fixes until 2014, many software vendors won't support their products on Windows XP for that long, nor will they support new versions of their software on older operating systems.
