I saw this yesterday after their product launches and had to take a look at the source. I'm actually really excited about this.
In Apple style they really made the presentation awesome. I had to do a double take because the video looked as if it was playing in Quicktime X within the browser.
I get a "download quicktime" message and a link to the QuickTime download for "Mac and PC". Then on the download page the options are OSX Tiger or Leopard (or later; http://www.apple.com/quicktime/download/) ... no link for other platforms. No mention of Linux.
Same here, even though I'm using Chromium on Linux with the chromium-codecs-ffmpeg-nonfree package installed (so it should support all HTML5 video formats that Safari does).
There don't seem to be any VIDEO elements on the page, so I guess they're only sending them to a limited set of "supported" browsers.
It's related to the format of the video rather than browser sniffing. Firefox only supports Ogg Theora for HTML5 video, but the video on the page is MP4/H.264. Dive Into HTML5 has more detail: http://diveintohtml5.org/video.html#what-works
Mozilla is fundamentally opposed to decency on ideological grounds.
They really should just do a generalized version of what Safari does -- call out to Quicktime / DirectShow / GStreamer, but they'll never do that, because it would invalidate their efforts to shove OGG down people's throats.
Barring that, they should do what Chrome does -- link in a normal copy of ffmpeg that's built without most of the codecs by default.
Instead, they link directly with liboggplay. You'd have to significantly fork Gecko in order to support anything but Vorbis and Theora in OGG containers. It reminds me of the way Stallman designed GCC's internal representations to be impossible to interface with externally.
If you're going to wank about respecting patents and copyright licenses, let them be enforced by the legal system -- don't do it by writing obnoxious code.
I actually saw this yesterday when I was trying to download the video for later watching when I was offline. It surprised me a little to see it on a production website, but I was thrilled to see it. It even has that "Quicktime X" look in Leopard, too.
