But you probably mean something along the lines of: "Increasingly, users are accessing the web from a mobile, therefore it's critical that your presence on the web is optimized for mobile devices. Studies have shown that 2/3rds of users will not return to a site that is not optimized for mobile."
That was floated next to a Flash video embed with no fallback. But here's the fallback on YouTube: http://www.youtube.com/watch?v=Ja7abx3OPOQ It was easy to find once I opened the whole presentation in a desktop browser with Flash support, click-dragged back to the page, clicked the magnifying glass icon to spawn the popup, then the More Info tab, then the YouTube icon in the lower-left corner of the video to 'view on YouTube'.
I'd send you a link, but there isn't one. It's all one URL. And you're probably not part of the 1/3 that will return to a site that isn't optimized for mobile anyway.
