Or another way to view it is that if you factor in Flash support for H.264, the only clients that can't view H.264 content are Firefox, Opera, and IE 8-or-earlier installs without Flash installed. I'm not sure what percentage of the market that is, but I'm pretty sure it's pretty small. In comparison, all mobile devices, game consoles, and Blu-Ray players support H.264, as do all Flash installations (including the one bundled with Chrome that users can't remove), and all installations of Safari and IE9 (when it arrives).
