When my Grandmother was 81 I bought her an iMac, so I could send her digital pictures and she could see my work. I'm a Mac user and wanted a machine I could help her with if She got confused. I ordered the iMac online and had it shipped to her. I called and said, "have the driver put it in the corner and I will set it up next week." She said ok. I got an email from her the next day. She got out the computer and set it up. Followed the simple instructions to get internet access and she was going. Let me qualify this story, my Grandmother never drove a car or had touch-tone phone service. She never used an ATM or Cable television. The main interface between her and the world was the newspaper. She lacked the mental model to understand how a computer is used and why. Apple's instructions and seductive packaging got her out of her comfort zone. She was very happy with the experience. I may be a nerd but my Grandmother was not. That's a success for an older age group.
