I'm not attached sentimentally to any cables. I'd love for audio, volume, skip, and microphone functionality to work with all my devices and all my headphones. Would it be annoying to lose compatibility (or require a converter) for all my existing speakers and headphones? Of course. I'd still take that penalty if it meant the overall experience was better and eventually more consistent.

Frankly I'm not sure 3.5mm is going to survive in the mainstream anyway. Bluetooth might eventually replace it for mainstream use cases.
