Internet Explorer 9

Internet Explorer 9 was released a couple of weeks ago and if you have Windows Update on, you most likely already have it, or will shortly!

Internet Explorer 9 has a host of new features, ranging from speed to usability to security.  Internet Explorer 9 sports more compact interface, with basically everything on one line, forward and back buttons; address bar; tabs; and home, favorites, and settings icons.  With Internet Explorer 9 and Windows 7, website can be pinned to the taskbar, which provides a simple single click access to your favorite sites.  Internet Explorer 9 will also be the first browser to support hardware acceleration (faster graphics!); you can check out some of the cool examples at the Internet Explorer Test Drive: http://ie.microsoft.com/testdrive/.

Also for those that care about such things, IE 9 supports HTML 5, CSS3, and a drastically faster JavaScript Engine!
As for my thoughts?  My experience with IE 9 has been overall positive.  IE 9 has been faster on my system, though not necessarily on loading pages, which is most likely caused by my slow internet connection.  What I find more useful are some of the new feature such as pining sites and auto fill in the address bar.
