Feedback from previewers meant they needed another cycle. That's good, since the same detractors tend to be the ones who accuse Google of shipping half-baked products.
There was a lot of negative feedback to this, and this is probably a good step. Its also nice to see the goodwill gesture of fulfilling preorders for free.
The headline is accurate and not inflamatory. Your proposed summary reads like PR puke on the other hand.
If you wanted a Nexus Q then you will not be able to get one. Simple as that. And this little exercise in product development is about as half-baked as it comes. You do product development/marketing BEFORE shipping not after.
From the article:
