Slashtop app $.99. (RDP app vs a browser, but gets the job done)
I watch Hulu and any site I want, flash video/sound and all. Hulu is about all I use it for, but it works much better than Skyfire imo.
I've used the iPad for probably 80% of my web viewing and anymore (outside of Hulu) don't even think about Flash or run into issues with a site not having it. Most flash based site's I visited such as ABC, CBS, ESPN etc... either have apps or have converted to iPad friendly sites.
