To me the iPod died with the introduction of the Touch which was a cheap iPhone, that had lower quality standards even in the area of sound quality. iPhones have no headphone jack so they're not suitable listening devices if you care about audio quality (or are willing to carry an external DAC). Apple Music makes nothing about managing music on any Apple device great.
M1 Macs are doing well, and still waiting to see what happens with iPadOS and if it can live up the the 'OS' name in terms of creation not consumption apps.
