This is the best evidence I've ever seen, I think, in favor of not worrying about "having a great launch/1.0 product". Even if you're Apple and the whole world is watching you keynote the product on stage, people will
still forget the first kinda-sucky versions, and instead remember the first
good-enough version, as the first version.
(Mostly because, for the critical mass of users, the first good-enough version is the first version; it's the first version their friends were excited enough to tell them about, so it's the first one they tried.)
Which is all to say: stop worrying about putting people off with a bad launch product. Ship the dang thing, and keep shipping it, and eventually, somewhere in there, the thing you're shipping will get good enough to get people paying attention. It doesn't matter what the early adopters think; they don't get to write history.
