If you just read one article about the iPad, make it Adam Engst's article on why the iPad is magical. He argues that the iPad is different from a computer or the iPhone or iPod touch in a subtle and special way: it becomes the app in a way that these other technologies don't. That was what I noticed when I watched the Wired video review. The iPad, Engst says, is like a chameleon or tabla rasa or blank slate that transforms with each app you use.
