I note that W3Schools.com posted their browser info for January, so I updated the graph. Firefox appears to continue its rise at the expense of IE6. Removing the WGA in October didn’t seem to have any effect. Is the out of place look-and-feel in XP a bigger issue? The rendering engine changes? Has basically everyone who was going to switch to IE7 on XP already done so? One wonders if the very slow (but steady) rise in IE7 usage over the last 10 months or so is due primarily to Vista adoption. There’s a scary thought for Microsoft. Let’s compare with the OS stats:
May 2007: 2.8% Vista, 19.2% IE7
January 2008: 7.3% Vista, 21.2% IE7
Change: +4.5% Vista, +2.0% IE7
So yes, it is entirely possible that all the IE7 growth is due to Vista… and yet if we are generous and attribute all of IE7’s growth to Vista (rather than XP+Vista), that implies that 5 of every 9 new Vista users visiting that site dumped IE7. Ouch. That does not bode well for IE’s future.
