Donna told me so.
Donna is my wife, who has been wrasslin' with a Windows machine for the past three years. During the winter, whiel we were away, she used my MacBook and found that the keyboard wasn't so terrible and unusable.
Then she was mousing around YouTube, looking for a video about a jewelry-making technique. She found it, and then YouTube showed her there were others, dozens of them. That's when the lightbulb went on.
She'd heard about the iPad and asked if she could watch these tutorials on it. "It would be so much more convenient if I could watch them while I'm working," she said. (same thing as reading a book and working along to the directions!). Yes, I told her. "Wow," she said, and immediately told me she wants an iPad for her birthday.
Since then, she's read more about the iPad; saw the Oscar night ad, and has been telling friends about the iPad. It reads books, you can do e-mail with it, it has lots of apps.
Bottom line: this non-computer person has become a tech Evangelist.
If the iPad can capture Donna's imagination, it will dot he same for millions of other people. They'll use it. They won't call it a computer. They will just buy it. It will just work.
