Will Windows Vista break all sales records?

Windows Vista could be the fastest selling operating system ever, reports InformationWeek, quoting Microsoft’s Jim Allchin :

Vista could be the fastest-adopted operating system in PC history, Microsoft group VP Jim Allchin said in an interview last week. About 475 million new PCs will ship within two years of Vista’s arrival, and Allchin said companies might upgrade several hundred million older machines to the operating system, which contains features that Microsoft can market to all its customer segments. “We haven’t had a product that does this in 10 years,” he said.

Windows and Office products accounted for 84% of MS revenue last year.
