February 2010 Browser and OS Market Share Study Released
Janco has released its latest Browser and OS Market Share White Paper. One of the major findings is the difference in acceptance of Windows 7 versus the the acceptance rate of Vista.
February 2010 White PaperIn the last several months Microsoft's browser market has continued to decay. Firefox and Google (Desktop and Chrome) continue to have the potential to eat away at the Microsoft browser monopoly. Users who move to Vista and Windows 7can more readily have multiple browsers on their systems and switch from one to the other quickly and with little pain. In addition with the release of the browser ballot option for the EU we forecast there will be a continual erosion of Microsoft's IE market share. Based on our test results current versions of IE and Firefox are significantly more robust than prior versions. In addition, IE 8 is feature rich and a step ahead of the other browsers. Chrome has major defects which limits its usefulness on all sites. Several of these defects are highlighted in this White Paper. Trends in Browser Market Share
