Another issue that comes up with portable devices is software fragmentation. "It's fine on day one; everyone will have the same version," Freimark says. "But some will upgrade and some will not upgrade. Some older devices can't be upgraded." Apple does a better job than most at consistent device upgrades, he says.
Airport food and beverage operator OTG has placed iPads at benches at some Delta terminals, including New York's LaGuardia and JFK airports. On a given day, 100 people might use one of these iPads, which raises the issue of how do you keep it from breaking, walking away and secure, with each user's personal data and Facebook password protected. "There's a whole wealth of experience that needs to go into that," Freimark says. "A lot of people underestimate how durable the iPad is when it's being passed around by a lot of people. They're concerned about security and breakage. There are good solutions for both of those things."
