Interesting: Google Apps has stated they will support the last major version, and the second-last of web browsers.
As of August 1st, we will discontinue support for the following browsers and their predecessors: Firefox 3.5, Internet Explorer 7, and Safari 3.
I suppose IE6 was around for so long that it’s easy to think of IE7 as being “new”. But in fact it’s five years old this year (official release October 2006), and was officially superseded two years ago.
Hopefully all those corporates who dragged their heels on IE6 can move a little faster off IE7.
