Hmm. I don't know. Whenever something new and different gets revealed, a lot of negative opinions (by that I mean more than usual) spread around because it's new and different. I like the idea of a foldable iPad-Mac hybrid, would solve most of the problems of people that want a powerful tablet that can also fully exert said power. Now you can have a tablet with true desktop-class apps.
And if it's just a foldable iPad, then there would be a lot of cool combos available. For example, want a true typing experience? Fold it like a laptop and use the bottom as a touch keyboard (knowing Apple, they won't do that because they need to sell Magic Keyboards.)
