After being released with much fanfare, Apple's smart speaker, with its gorgeous design and flawless acoustics, appears to be going over less like the iPhone and more like Snap Spectacles.

Here's our Thinknum data trail of the sales ranks at Best Buy for HomePod's two different color configurations. After a promising start, it never cracked the top 100, and has been slowly subsiding:

What went wrong? Judging from industry reaction, the main points are:

Bloomberg's Marc Gurman says previous Apple tech - the iPhone, the iPad, the Apple Watch - brought something new to the category that leapfrogged the competition, but they failed to do that here. "They've had all the components, but they're bringing them to market three years after Amazon. Apple missed out on a category that they should have been first to and they should have won."

And that's been showing up in tanking sales. According to Bloomberg, Apple has already cut back on its manufacturing orders, and Apple Stores' back rooms are filled with unsold inventory. 

At Thinknum we don't have access to Apple's in-house numbers, but we can offer the contrast between the two HomePod stats with the dozen Echo and Sonos smart speakers in yesterday's Best Buy sales ranking (and those are just the best-selling versions of the Echo line - Amazon has a lot more different styles and configurations available):

And here are the past three months' data from Amazon.com, where various Echo products have totally dominated the top 100 of the electronics charts - and HomePod hasn't even registered:

According to Slice Intelligence, the Homepod did very well the first few days after its release - quickly jumping to 1/3 of smart speaker sales in the last week of January. But between word of mouth on its limited features, and the extremely limited market, that pent up demand quickly petered out.

Here are Slice Intelligence's numbers for all smart speaker sales so far this year, and it ain't pretty.:
