Vista adoption rate 'twice as fast' as XP's
Back in March, Microsoft boasted that it had already sold 20 million copies of Windows Vista, and that its new operating system was on its way to becoming the fastest-adopted version of Windows ever. As CNet reports, Microsoft says that in the following month and a half, it managed to sell nearly 20 million more copies of Vista. At the Windows Hardware Engineering Conference in Los Angeles today, Microsoft Chairman Bill Gates explained, "As of last week, we've (sold) nearly 40 million copies." According to Gates, sales of 40 million mean Windows Vista is being adopted "twice as fast" as Windows XP—at least for the three and a half months after launch. For reference, it took Microsoft six months to sell 32 million copies of Windows XP after the operating system came out in late October 2001.
