I guess the wager is all these people who wanted an iPad Mini but didn't buy one, as they only want it if it can unfold into one on the go?
I'm sure there are many who may want that ...
But it makes for a very heavy brick in your pocket, for the price of a full blown really nice MacBook Air 15".
Nothing is really for "free" here, even on foldables.
You get the smallest iPad when you unfold, and a heavy brick of an iPhone, missing some key things, the rest of the time.
