An example of what I mean: I wanted to listen to this Yale course on listening to music: http://oyc.yale.edu/music/listening-to-music/content/downloads They offer the course in quicktime video, and mp3. I realize you can probably download to a PC and then transfer, BUT many people including myself run an iPad only. I understand one reason may be because Apple wants you to buy everything from Itunes rather than having people pirate things. However not all quicktime videos are pirated, and many mp3s such as the above example are free. I see this as a significant weakness of the iPad. Will this be addressed in OS4?
