I recall them being a slower burn that first year, still a great year but not to the degree of their other new products; but in under 3 years they were part of what I at the time called the San Francisco uniform:
1. AirPods
2. Apple Watch
3. An iPhone, if not visible was implied.
4. A messenger bag, backpack or purse.
5. Sunglasses
6. Some kind of mask to filter out the smog from the fires in 2019.
