Microsoft today revealed that Internet Explorer 9 is now used by over 20 percent of all Windows 7 users, according to data from Net Applications. In the US, it's even higher: IE 9 is used by over 28 percent of all Windows 7 users.
On that note, Firefox usage was also flat, Chrome usage went up slightly from 14.33 to 15.51 percent, and Safari usage was unchanged month over month. In other words, there were no major changes at all. So the IE 9 stuff is, in fact, news. It's the only thing interesting that changed in web browser usage last month.
