I haven't heard anyone else mention something like this, so I'm going to put this out there. There was something posted in the blogosphere about Apple patenting, or trying to develop a way to overcome an inherent design ceiling. The current family of iDevices are limited in how thin they can be by the size of the headphone jack. The devices have to be at least a certain thickness because of the jack. With all of Apple's focus on the purity of design, it amazes me that this has not been addressed yet. When you dance, run, cycle, etc. the single thing that gets in the way, that takes away from the sleek trimness of the compact devices are the earbud wires. You have to thread through special ports on backpacks or clothing, and you have to make sure they don't get hung up on things you walk by, your elbows, parts of your bicycle, around the shift knob in your car, etc. I'm wondering when Apple is going to find a way to get the music from my iDevice to my in-ear pieces (whether they be like buds or like hearing aid inserts) without wires.
