If we were hacking on other senses too I'd love the native ability to find north. As far as I know we don't have the technology for that yet.
As A kid I used to wonder if eating crushed up magnets would turn me into a homing pidgin! I saw a video about those magnet implants about a year ago. I think the novelty would wear off being able to pick things up and it would be a real nuisance around any machine producing ferrous dust and/or small slivers.
