Nope. Not a typo. From the linked post by Horace Dediu:

The Apple Watch is now bigger than the iPod ever was. As the most popular watch of all time, it’s clear that the watch is a new market success story. However it isn’t a cultural success. It has the ability to signal its presence and to give the wearer a degree of individuality through material and band choice but it is too discreet. It conforms to norms of watch wearing and it is too easy to miss under a sleeve or in a pocket.

First things first. Take a look at the bar graph in Horace’s story. The iPod is red and the Apple Watch is orange. As you made your way, quarter by quarter from 2009 to 2018, you’ll see iPod revenue slowly disappear, declining into the other category, then see the mighty emergence of Apple Watch, way bigger than the iPod, revenue-wise.

OK, back to the post and that weird title:

Not so for AirPods. These things look extremely different. Always white, always in view, pointed and sharp. You can’t miss someone wearing AirPods. They practically scream their presence.

For this reason wearers, whether they want to or not, advertise the product loudly. Initially, when new, they looked strange, even goofy. But the product’s value to the wearer overcame any embarrassment and for those courageous enough to wear them, they became a point of pride. As all things distinctive enough, the distinction rubs on the user and that distinction begets new users and new distinction, and so on. So now we have a bona fide cultural phenomenon.

And:

The only thing which AirPods do remind me of is the original iPod. The iPod-and-white-earbuds had a similar signal/function ratio. Looks distinctive, works well, nails the job to be done and is self-describing. The “iconification” of white was the phenomenon of its decade.

AirPods + iPod = AiriPods

Good headline work there. Read the rest of the article. Lots of interesting thoughts, especially about the decision not to mess with a good thing when moving from the original AirPods to gen 2.
