I'm always curious to see what these statistics would look like if they were broken up by user demographics. And also by HTML5 feature. Sure, 1/4 of users might experience problems with HTML5. But what really matters is what percentage of your target market will experience issues with the HTML5 that you use on your site. Conversely, if you're targeting smartphone users then you should probably be developing a mobile version of your site anyway. And if you are doing that, then having Flash on your main site won't create such a problem with reaching mobile users. Not that it doesn't get rid of the need to make sure your site degrades gracefully.
