Linux market share
Right now, the market share of Linux is noted by many sources as between 2 and 3 percent. However, other sources dispute that. For example, on another forum I saw that a BBC report mentioned that it is at about 6% (this was in 2007).
I know there are different ways to track market share data, and to me NetMarketShare, for example, seems to be more accurate than DAP as it counts unique users, not actual visits. But is safe to believe that the market share is between 2 and 3 percent?
