Yes, I agree. Ship early and ship often, but understand that it probably won't be "good" for some time. Back when Microsoft shipped, the joke was that it took 3 versions to get any good at all (Windows being the perfect example).
Those that do versioned the first version of Windows NT "3.1", to give the very impression the grandparent mentioned: that it had been through three major releases (and a service pack) already, making it pretty darn good. Whether or not the experience felt like a 3.1 is left as a question for the user.
