Earlier this month, my octogenarian mother had to give up her defunct decade-old MacBook that she inherited from my father. Before 2007, she had never sent or received an e-mail – so high tech is still new to her. My sister and I were a little hesitant to move her from her laptop to an iPad due to the UX change, but it's working out better than expected.
Today, she called me asking about the Epley Maneuver on YouTube. She called on a POTS line and then I switched the call over to a FaceTime video call, which she enjoyed. After I told her how to watch the YouTube video that I sent her ("Simply click the link in the e-mail, mom.") I then told her how to hang up and she enthusiastically said, "This is soooo easy." There was almost a hit of "why didn't you switch me to an iPad sooner" in her voice.
Innovation is something that reduces the cost of a transaction in terms of time or money. And that's exactly what the iPad has done for my mother.
