One advantage the Kindle has over the iPad, and just about any smartphone, is its free mobile Internet access. "We thought we might be able to exploit this access for another use," Megan von Isenburg, associate director of public services at Duke University Medical Center's library, said at a mobile healthcare conference in Baltimore last month.
