One rumor I’ve heard from an industry insider is that Hulu is working on an iPad-friendly version of its site that should be ready by the time the iPad hits the market. Hulu itself is still vague about its plans.
Hulu is a major source of online videos direct from the content providers (i.e. quality streaming videos instead of hacked, malware ridden stuff), so having it on the iPad will provide a lot of added value. I still hold that the apps customized to take advantage of the iPad will be a major factor in driving sales.
