You cannot get real feedback on a new consumer product before shipping the whole thing; feedback starts when somebody spends their own money on it.

And if you're doing a 1.0 and the world hasn't seen you, you're not going to get that from consumers, ever. You have to ship it, and you have to build the entire kind of ecosystem so those consumers see it in the fullness so that when they do the evaluation and they spend their own money, then you're getting real feedback.
