In the graph, there is a sudden change in 2005, where (I guess) mobile devices were added. What I don't get is how Apple jumps to 21%, given that the iPhone was not introduced before 2007. Edit: from the linked Seattle Times article: I asked Goldman Sachs about what happened in the 2004-2005 time frame -- as seen in the above chart -- that made Apple's vendor share jump, Microsoft's share plummet and the "other" category to go from zero to 29 percent. Goldman Sachs replied that it has to do with more mainstream adoption of non-PC consumer computing devices but declined to elaborate beyond that.
