I happened across this incredible presentation by M. Jackson Wilkinson on HTML 5 and CSS 3. It's a comprehensive look at the coming changes to HTML and Cascading Style Sheets. It's hard to believe that HTML 4 is over 10 years old already!
Browser support for HTML 5 will continue to drive more and more applications online. It appears the days of buying and installing software off of media are quickly becoming a thing of the past. The ability to develop and release incredible designs and applications will become easier… with timelines and resources shrinking.
