Do you expect those of us who have been bluetooth-only to go along with this?
I get the DRM reasoning. It makes sense to be worried about that. But I also don't like how physical connectors tend to break. I used to go through a headset every month because I'm pretty rough on devices; the cables always broke. Some years ago I switched to bluetooth headphones and that problem stopped. Entirely. I need to make sure I keep them charged, but it's well worth that hassle.
What this means is for my current and previous phone, I have never plugged anything into the headphone jack for the entire time I've had the devices. Which means I don't need that port. Which makes it feel about as useful as a PS/2 port on a modern computer.
