A failure in what way? You are assuming this because they discontinued the product, but that could have been due to the supply chain issues and the need to free up productions lines. Apple has never released unit or gross sales for the product, so it is presumptuous to think that it was a failure.The first gen was a commercial failure. Don’t see how this one wouldn’t be, seeing as it’s more or less the same product, years later.
I have to say, this Homepod (to me) is one of the strangest product releases Apple have ever done, since I became a follower back in 2004.
