Jason Snell, Macworld:

Sure, a few of us lucky souls were able to listen to a HomePod at Apple’s developer conference, but nobody outside of Apple has talked to one or picked one up. At the risk of stating the obvious, that’s because this is a product that’s not finished yet. Apple doesn’t want to publicly commit to a feature and then realize it can’t ship it; the product as the company conceives it today may not be the product that ends up in customers’ hands in December.

Lots of detail on what we know and what we still don’t know. Good read.
