''More than 140 million Vista licenses have now been sold, which averages out to around three copies every second since it went on sale last January.
"That's a very rapid sales rate," said Bill Gates in a news conference, reports the Wall Street Journal.
However, critics are quick to point out a couple things that make the Vista sales number defy actual consumer demand. First off, almost all new computers come with Vista pre-installed, so a new PC equals a new license of Vista.''
