Internet Explorer 9 Beta is set to release on September 15, 2010 after much indecision on when.

The preview demo was NOT the beta, it was supposed to give web developers and interested enthusiasts an early preview of the upcoming Internet Explorer 9. HTML5 is just around the corner, so Microsoft’s next version of the Internet Explorer will include improved support for it. It will also be a lot faster (probably up to 7-10 times faster)! Thanks to the new Javascript-engine Chakra (that gave Opera 10.5 quite a nice boost), IE9 will be faster than ever. Hardware acceleration is another great feature of the Internet Explorer 9 that will boost the browser speed.

•Hardware Acceleration

Web developers have been waiting for this. There are thousands of methods to achieve rounded corners via CSS or Javascript, but even the Nifty CSS rounded corners are far from being the perfect solution for rounded corners, but the IE9 will include more CSS3 standards that support perfect drawing of rounded corners.
