Microsoft delaying Vista again?

The wait for Microsoft’s delayed Windows Vista could be even longer than expected, according to a research report issued this week by research group Gartner Inc. A Microsoft spokeswoman however claims that everything is on schedule with its march announcement.

Vista is the first major overhaul of its operating system, which sits on 90 percent of the world’s computers and accounts for nearly a third of Microsoft’s total revenue, since Microsoft rolled out Windows XP nearly five years ago.
