I find most people I show it to are afraid to touch it. It's like they're afraid they'll break it or touch the wrong thing. I think a lot of people are programmed to "not touch glass" so it feels kind of weird at first... Maybe?
Some of my happiest moments since launch day have involved letting people hold my iPad and just have a go at it. I love to see their faces light up when they realize it isn't a push thing, and how responsive everything is. I especially love when they ask me how much it costs, and I tell them, and they're like, "that's a good price!". I feel like the world will have iPads someday.
