Ustream, already available on iPhone, Android and Honeycomb tablets, is finally bringing its streaming content to the iPad. What's even better is that the Ustream app supports AirPlay so you can beam videos to bigger screens.
Plus, if you have an iPad 2, you can broadcast your own videos with either camera (if you're into that kind of thing). The AirPlay support is especially nice because while the video is projected onto your TV you can still use your iPad for chatting and social stream. Free. [iTunes]
