The great thing about the 3.5mm and 6.35mm jack is that I can use old hardware that still works great with new headphones. The equipment I spend money on lasts and continues to work as I upgrade individual parts over a long period of time. The consumer wins. OTOH, you can't argue with their business model! Decades-old standards are meant to be deprecated, especially at the expense of the consumer. /s
