Interesting, but I shudder at the thought of yet _more_ designed-to-be-disposable stuff... I am still waiting for body-generated electricity a la Neal Stephens

Interesting, but I shudder at the thought of yet _more_ designed-to-be-disposable stuff... I am still waiting for body-generated electricity a la Neal Stephenson (I think - Diamond Age) - Tiny wires getting electricity from the human body via skin penetration to a human electrical source. Just stop before we get to The Matrix. :)
