Honey, I Shrunk the eLearning: "The kind of media-rich presentation features necessary for effective learning – features such as animation, simulation, graphically enhanced scenarios, video and audio – have not been possible given the small screen and limited memory of handhelds. This has been changed by a new generation of PDAs."
Comment: Several years ago, our department completed an evaluation of the role of PDAs in learning. The end result: PDAs are second-choice devices for learning. If other options exist, they will be used first. If not, PDAs will do. It is interesting, however, to note the number of functions now being performed on cell phones. It's possible that "the small screen syndrome" that limits PDAs for learning will end up being a generational (not device) issue.
