Back when I worked for a digital agency the number of requests I used to field from non-technical clients asking us to 'update' their sites by creating a carbon copy of their flash animations in HTML5 was staggering. That in itself wasn't really the issue, the issue was the misconception amongst non-techies that the role of HTML5 is a universally accepted flash replacement.
While accepting that it is not appropriate for every situation, I believe that the HTML5 canvas/video/audio/svg/dragdrop/storage elements are specifically targeted at replacing flash/silverlight so I can see how non-technical folks might get confused.
