Dammit. I keep resisting the lure of the iPad, but when jwz weighs in... Must. Wait. For. Next. Version. You know, the smaller one with the front facing camera. So my kids can do FaceTime with their grandparents. Or the one with a (dare I hope) retina display. I guess that's probably a few versions out.
Those aren't things you can explain — you have to experience using the iPad for several days to understand. It really is a different device from everything we are used to.
