Those are all cool, if you're sick or disabled in some way. What about for those of us who are healthy as a horse and want to supersede the natural state? What if I want to be able to sense EM fields, or put a sensor in me to monitor my sleep to avoid the hassle of a headband and a now-super-expensive Zeo, or put a bluetooth transmitter in me to ease data management between internal and external devices, or put a GPS sensor in me, or put a gyro&accelerometer in me that lets me do gestures independent of a wiimote or kinect, how about RFID in my hands and forehead? Of course those things aren't the coolest imaginable, but some things I can imagine would be really quite hard with the limitations of flesh. I'm currently content to be hopeful for mind uploading, then using artificial/robotic/simulacratic bodies of various sizes with lots of neat features for the times a version of me wishes to explore meatspace...
