Yea, it's pretty funny seeing all the posts here from people who cannot fathom why a product like this exists.
It's pretty eye opening really. If it weren't for seeing someone close to me do it, I'd be in the same camp, wondering who in their right mind would use their laptop like that.
I've seen someone close to me do it, and I still don't understand. I've asked her to explain why she fumbled around trying to perform a simple cursor move instead of moving the mouse, and I got a vague "it's easier" (it wasn't easier).
Same here. I couldn't understand it until like you and the comments before, saw younger generation all thought screens by default should be touchable, and other people casually scroll on the display and then return to keyboard for typing.
