According to Net Applications, IE 6 accounted for more than 26 percent of the browser market in June 2008, while IE 7 was used by over 46 percent of all people on the Web. If your PC runs Windows 2000 or an earlier version of the OS, you can't upgrade to version 7 of IE. Unless your boss insists that you use the older version of the browser on XP or Vista, you've got no excuse for not upgrading to the safer IE 7.As a blog company, browser market share is something we keep an eye on because it helps shape our testing policy. We have to make sure that both our blogging features work properly on supported browsers and that blog pages look right on them. We choose which browsers are supported based on market share.
I second O'Reilly's upgrading advice because not only will you get a more secure browser by leaving IE 6 behind, you will have a better web experience because IE 7 is much better at complying with web standards.
