How many Sony Walkman tape players and their clones did I break and where did they break? The headphone jack.
How many headphones have I broken and where did they break? The headphone jack.
As a student playing around 'on the decks' I found that anything with a headphone jack was liable to be responsible for that mains hum.
I have fond memories of using the headphone jack of the 32x CD ROM that was in the front of that 'Compaq' PC that cost many thousands. But when was the last time I touched a CD? So that is another headphone jack we thought we needed but didn't.
Had we moved to a magnetic latch as per the Apple power arrangement then I think that I would have got burned a lot less with the soldering iron and the purchase of hi fi kit and caboodle. Maybe with some optional VGA style screws if you really want the connection locked down hard. This could have been a much more 'jogging friendly' solution, waterproof too.
I mourn the loss of analog audio but not the headphone jack. Maybe the latter is responsible for the demise of the former and maybe there was vested interest in the Walkman era in having the universal but breakable headphone jack.
Incidentally the headphone jack seems much better engineered in computers and phones than in 1980's era Walkman style tape players. Maybe there was some lightbulb style conspiracy to ensure that headphone jacks only lasted '1000 hours' before failing, therefore maintaining sales of new tape players.
