I don't understand the form factor in this space. When walkmans were popular no one was trying to mount the tape decks to our heads. Couldn't they make some glasses that only had displays and run everything (battery, compute, etc) from a phone that was WIRED to the glasses? No mattery how much advancement in microprocessor and display tech happens I'll never want the weight of a battery on my face. Heck, normal glasses are heavy enough without adding any extra bulk. So until medium range wireless power transmission that can be safely beemed at my head becomes a reality I think someone should work on optimizing a portable wired solution.
