Canonical reported that there are 12 Millions active users for their Linux distribution, Ubuntu. In 2008 Canonical estimated 8 Millions users, this means a grow of 50% in the last two years.
Chris Kenyon, vice president for OEM at Canonical said: "We have no phone home or registration process, so it’s always a guesstimate. But based on the same methodology that we came up with for the 2008 number, our present belief is that it’s somewhere north of 12 million users at the moment".
