If we can get IE and Safari to finally implement WebM/VP8 support after realizing that there really is no patent risk here (well, no risk greater than using ANY codec whether licensed or not), we'll finally be able to use the HTML video element and expect the latest version of all major modern browsers to support that video format. No more user agent sniffing and switching over to H264.

Problem being, people will be running IE8, IE9, IE10, older Firefox, older Safari for a decade or more from now, and those people still won't be able to view the WebM video, even if Microsoft and Apple implement it in the very next release of their browsers. I hate people who don't upgrade their software.
