Vista Sales Halved
Microsoft today revealed that it had sold 40 million copies of Windows Vista in the 100 days since its late-January debut. Company founder Bill Gates made the statement at the opening of Microsoft's WinHEC conference, and noted that many of the copies sold were versions above and beyond the standard version; 78 percent of copies were for Home Premium or higher, he said. The figure was cited as proof of an increasing shift to digital media in most computer users' lives.
While significant, the sales point to a rapid slowdown in adoption of the new operating system. Microsoft had observed that it sold 20 million copies in the first month, which doubled XP's achievement but now indicates that the average number of copies sold has been cut in half during March and April. The firm has so far declined to compare its most recent figures with the relative size of the market today or to any decline that may have occurred during XP's 2001 release.
Although heavily anticipated, Vista has been plagued by sporadic issues with missing drivers or incompatible software that have caused hesitation in some buyers.
