É bom lembrar que o site é acessado, principalmente, por pessoas envolvidas no desenvolvimento de páginas da internet, portanto, um público bem específico. De acordo com o sítio, não se pode confiar nas estatísticas, pois poder estar erradas mas, de qualquer forma, é uma curiosidade ver que, ao contrário de outras estatísticas que mostram o Linux como tendo cerca de 1% de participação, essa mostra um decréscimo constante do Windows, uma estabilização do MacOS e um crescimento constante do Linux, hoje com quase 5% de participação.

O site tem muitas outras estatísticas interessantes, vale a pena conferir: http://www.w3schools.com/browsers/browsers_os.asp
