Presently, all digital mathematics content made available to students from publishers requires an internet connection. And is an iPad app going to contain an entire semester's worth of video content? How many gigs would that take? The iPad doesn't have enough disk space to hold more than a couple of books with all of the lecture videos contained within it. As such, isn't a better idea to allow <embed> tags and have Youtube videos played from within the iBook accessing the internet? I think so.
