I think one of the issues is premature optimization/minimzation(?) . All the wearables so far that feature some human interactive display are essentially cramming the mobile concept into different device classes. Take the AR glasses , they are essentially a computing unit output display , input (joystiicks/sensors) all being crammed into one unit with a powerpack to drive it all. I believe the desktop concept, or in this case 'Walkman' concept would be better fit for wearables .Where one can separate the processing from the display/output and power each separately.Having a cable from your hip pack to the headunit is not so strange/difficult as previous gen of walk/discmans can attest. However the current ruling desing is wireless everything , super slim devices and all unified with the power supply.
