Just noticed that Stanford has an iPhone app (iStanford) and that MIT has a Web site formatted for mobile devices. Students can search for classes, add and drop, and more. Smartphones double as reading devices and some can even access Blackboard.
While I suspect the iPhone won't replace the traditional classroom, it's worth thinking about as an "access extender." but is even that kind of thinking too narrow?
(BTW, this post was Sent from an iPhone.)
