Microsoft will release Internet Explorer 9 on Monday. Says Webmonkey:

In terms of web standards IE9 is light years beyond anything Microsoft has previously released. Granted, Firefox, Opera, Safari and Chrome are somewhat further along with the more experimental features of HTML5, but given IE’s dominant market share worldwide, IE9 should be a huge boon for HTML5 adoption (provided users upgrade).

By the sounds of it, Microsoft, after 10 years of trying, has finally produced a decent browser. Take a test drive.
