According to the latest results of the desktop OS market share in the US for April 2011 collected by StatCounter, it looks like people are finally leaving Windows XP behind and getting an upgrade to Windows 7. For the first time since it became the most popular operating system around, Windows XP’s market share has been trumped by Windows 7. Windows 7 is now used on 31.71% of desktops in the US, while Windows XP has dropped to 31.56%. Now the lead isn’t a lot but it does show that Windows XP has finally peaked and is on its way out now. Windows Vista is at third place with 19.07%, Mac OS X at fourth with 14.87%, Linux is last with 0.70% and Other/miscellaneous operating systems make up 2.09% of the chart. It makes you wonder if there are users still on Windows 3.1 out there. How many of you are still haven’t made the upgrade to Windows 7 from XP or Vista?
