While the iPad can prove to be a welcome distraction thanks to the bevy of games and creative apps available, several top business schools are measuring their effectiveness as teaching tools, not toys. "A good e-reader eliminates the students' need to use lab printing resources, the cost of which is often deferred to the students through per-page printing fees," says David Schuff, associate professor of management information systems at Temple's Fox School of Business. "These savings are in line with the sustainability efforts taking place in universities, like Temple, reducing our own printing costs and paper waste."
