These would be enough to steer away from flash imoHere are just a few:
- The site won't work on practically any mobile device (smart phones/tablets), Linux support isn't too good either AFAIK.
- Flash sites are not SEO friendly - the site's content doesn't get indexed by search engines, also you typically don't see deep links in Flash sites.
- Flash sites typically load significantly slower and require more data to be downloaded
- Flash frequently shows major security issues
- It screams "Hello, I'm from 1997"
How about using flash just for the mp3 player, video player, or image gallery? I will see if I can find alternative players to use in html5 first though.
