John Gruber has an opinion in his piece showing how to load HTML5 video instead of Flash in Safari on OSX.
That this works for so many sites shows that Safari on Mac OS X is perfectly capable of playing a lot of video on the web that seemingly requires Flash. Web developers should start serving video via the HTML5 <video> tag by default, and fall back to flash if the <video> tag isn’t supported.
It’s pretty clear Safari is a tiny proportion of the browser market, but what would be the impact if webservers took his advice globally? On other browsers?
On Adobe’s share price?
