As I say, I can live with a dongle for 3.5mm or serial (despite it being a regression), it's just another straw.
The certainty and simplicity of an audio jack is not valueless though, no matter how many people on HN say it is.
Nobody is saying that audio jacks are valueless in general, just that it's reasonable for a mass market device where it has value for a small % of people to not have it.
