One guy’s story of trying to go Flash-free:

For me, the conclusion after February was clear. I missed out on a few things that annoyed me intensely. Most of the things I missed out on were videos on websites like TED and the New York Times. I had some catching up to do after February. With the help of ClicktoFlash and Youtube and Vimeo’s HTML5 players I was able to watch most of the video content out there, but there is still a lot that you can’t watch without that little plugin. I also ‘missed out’ on a truckload of so-called ‘rich advertisements’, which I absolutely adored.
