it suddenly occurs to me that the push to abandon the 3.5mm audio jack could, in part, be an effort to close the analog hole.
Right now, you can take any device with a headphone jack, plug it into a laptop with a microphone jack via a plug-to-plug audio cable, and obtain a decent-quality DRM-free reproduction no matter how encumbered the source file or player happens to be.
Try doing that again in 5-10 years when all headphones only have digital interfaces and all players only accept Approved accessories.
Sure, DACs with standard output connectors are easy to come by now, but if the industry is successful in shifting focus to fancy digital accessories, that might not be so in a few years.
