Some websites still require Flash, mate. Hard to get around that until they find another way to proffer their wares, sad to say.
Not ones of any value, I've found. If they still insist on FLASH they don't get my business. Monst of what I've seen that require Flash are ads. When I run across a major website that still requires Flash, I write to the CEO of the sponsoring company, not the IT guy building the site, he's too stupid to write to, telling him how his IT/webmaster is giving his company a bad reputation by forcing potential customers to load a malware magnet on their computers to buy his products or use his service. I'm quite specific about it and include links to articles on the failings of Flash and the constant number of zero day vulnerabilities and exploits. I also demonstrate there's a reasonable substitute that exists in the HTML5 standard code. I then ask "Are you in the business of selling your products/services, or in the business of supporting and advancing Adobe's bug filled product?" You'd be surprised how often that gets results and how quickly!
