speaker : Stephen Sinofsky
Building Internet Explorer 9 includes a huge improvements in web standards and HTML5 (actually putting a focus on the acid3 test). Also includes JavaScript performance increases. Currently gets a 33/100 on the Acid3 test.
IE9 now renders text with Direct2D as opposed to GDI, this makes JavaScript effects less choppy and letters/graphics look smoother.
