I call bullshit on IDC's figures. If you take public-facing websites -- something that can be checked -- MS has a 20% market share[1]. Some of these are multiple sites on one server, and some are multiple servers on one site, which probably cancel each other out so c.286M sites is roughly the same number of servers. By contrast, IDC's figures are for a total of less than 2M servers sold per quarter. If each server lasts for 5 years, that means there are a total of 40M in use worldwide, which is way too low. 1. http://news.netcraft.com/archives/2011/02/15/february-2011-web-server-survey.html http://news.netcraft.com/archives/2011/02/15/february-2011-w...
