In recent months, the Internet Explorer 9 (IE 9) became a hot topic for discussion on the internet. Some popular tech blogs have begun downloading the early version of IE9 to try out the new features and to my surprise, IE9 impresses! This shows that Microsoft Internet Explorer is still the browser to beat eventhough it has lost market share to worthy competitors over the last few years. To those who have yet to take the preview version of IE9 for a spin, download it here.

HTML5

IE9 is supporting a number of new HTML5 elements such as

1. h.264 video  and embedded audio
   HTML 5 core objective is to reduce the need for proprietary plug-in-based rich internet application (RIA) technologies such as Adobe Flash, Microsoft Silverlight, Apache Pivot, and Sun JavaFX. Hence new elements like <video> and <audio> are introduced.

2. SVG (Scalable Vector Graphics)
   Scalable Vector Graphics (SVG) is a new graphics file format which can used to create dynamic and interactive graphics without the need of plugins.
-
3. CSS3 support
   IE9 supports many components of CSS3 including CSS3 selectors, opacity property, fonts, colors, borders and rounded corners. More will be supported by the official launch.

Performance

According to IEBlog, IE9 has a new JavaScript engine named “Chakra”. Here’s a chart of IE9′s performance on a particular industry benchmark for JavaScript performance, the Webkit Sunspider test:

As you can see,  IE9 shown great improvement in rendering speed. Though it could not outpace Safari4.0, Chrome and Opera 10.7, well , at least it is getting closer. Check out how bad IE8 performs.

Goodbye XP!

Unfortunately, it is now official that IE9 will not support XP and requires Vista Service Pack 2 or later. To millions of XP loyalists out there (including me), it is time to upgrade
