It's kind of funny watching people who've never used one try to adjust to it. My kids grew up with them and wouldn't use anything else. They have them on their laptops too. I hate laptop touch pads, the single worst UI ever put on computers.
Yeah, I mean, I try to explain the appeal, and nobody is even willing to give it a shot. I can't help but laugh when someone tells me how their Magic Trackpad thing is so much better. The precision is terrible, it doesn't improve on all the standard mouse type of constant wrist movements, and so on. Sometimes I joke that trackpads were meant for species that haven't evolved thumbs, or haven't learned how to use them. :)
