Browser Market Share

In the last several months Microsoft has stabilized its browser market.   Firefox and Google (Desktop and Chrome) are still forces that could eat away at the Microsoft browser monopoly.   So far user acceptance of Vista has been slowed by the lack if user acceptance for the new OS.

Live update did not help in accelerating the acceptance of IE 7, plus with the slow acceptance of Vista individuals and enterprises are not moving to the new version as rapidly as Microsoft would like.   An added kicker is those who move to Vista can more readily have multiple browsers on their systems or switch from one to the other quickly and with little pain.   The cost of doing that is minimal.

Google with it browser Chrome will be the next challenge for Microsoft to face.   Based on our test results IE 8 and Firefox 3.5 are significantly more robust than prior versions. The current version of Chrome is not yet as stable.
