OneStat.com, today
reported that Microsoft's Windows operating system has a global usage share of 97.46 percent. Microsoft's Windows still dominates the global operating system market. The global usage share of for Apple's Macintosh operating system is 1.43 percent and is the second most popular operating system in the world. The three most popular operating systems according to OneStat are: 1. Windows 97.46%, 2. Macintosh 1.43%, 3. Linux 0.26%. All numbers are an average of the last 2 months. The other big statistics company, StatMarket, placed (in June 2002) Microsoft at around 95%, MacOS at 2.4% and Linux around 0.35%.
Web Site Boring (StatMarket) and OneStat.com report this stuff over and over, trying to sell their over-priced and in my experience very unreliable services.
Imagine if someone told you that there are almost no Ferraris or HGVs on the road, and then you found out that they based this on counting the vehicles that were seen at their chain of filling stations which mostly (1) Only carry "standard" fuel and (2) Aren't on long distance HGV routes
Both these stats companies serve primarily "Me too" web sites and the endless supply of "My {kitten, newborn child, wedding}" pages that people mean to update but never do. This inevitably distorts statistics. If you run a "Me too" web site then maybe this is interesting data, if you want to know what the world uses to browse the web it's nearly useless.
