Website Hosting On Amazon S3 vs. Dreamhost

Hello: I've been using Dreamhost a long time, but looking around at other hosting (too many viruses/hacks and downtimes, email problems etc.). Wondering if anyone here has used Amazon S3 for static (or dynamic) website hosting - emails, audio storage (they don't really allow podcast file hosting), maybe some video?

I would also love to stop paying Dreamhost their annual fee regardless of bandwidth - Amazon seems to charge by bandwidth vs. month or year.

THANK YOU
