The Tob cable is the last cable you will ever need, supposedly. It promises faster charging, faster file transfer (vs usb2) and hd video. "The TOB cable connector is easily plugged in and it’s circular design means there is no wrong way, it unplugs easily and protects your connectors if someone pulls on the cable." this is the first mildly successful Icelandic kick starter project.
