40M Vista Licenses in 100 Days
Gary writes "In the first 100 days since its launch in Jan 30 Windows Vista has sold an astounding 40 million licenses. Bill Gates gives the credit to accelerating consumer shift to digital lifestyles which has made it the fastest selling operating system in history. Surprisingly the more expensive premium editions accounted for 78 percent of Vista sales. With around 400,000 licenses a day new Vista users will take 8 weeks to beat Mac users, 4 days to exceed Mac sales and 3 days to exceed Linux desktop users."
You are assuming its Roman numberals. Its not. Its engineering notation. M (Mega) = 10^6 k (kilo) = 10^3 m (milli) = 10^-3 etc... If you get a 512Mb memory key you don't say it can hold 512,000 bytes do you?
