I am excited to deliver this quick screencast on  Internet Explorer 8 beta 1. In this screencast, I show some of the great enhancements that IE 8 will do to help solve some common problems around CSS development as well as some new features leveraging HTML 5.  Check out the screencast below, remember double click to go full screen:

In the screencast I showed how IE8 is going to help with Cascading Style Sheets (CSS) 2.1 and browser  interoperability.   IE 8 will render in standards mode but with this meta tag:

     <!-- Use IE7 mode -->  <meta http-equiv="X-UA-Compatible" content="IE=7" /> 

developers can render the page in compatibility mode.  For a better Code Sample take a look here:  Defining Document Compatibility

While IE 8 is being designed to work with CSS 21, we are also forward looking to CSS 3.0 and some of the most popular tools.  To learn more about compliance check out the white papers here: CSS 2.1 Compliance

In addition the CSS demos, I show  some exciting HTML 5 features, specifically HTML 5's support for hash functionality, which allows some interesting interaction inside your AJAX applications.  Also I show some of the support for connection events as well as HTML 5's DOM storage capabilities.  These allow you to really have a near offline experience with IE.  To learn more about the improvement with IE 5 and AJAX development take a look here:
