When Tod Kurt of ThingM recommended these reversible Micro USB cables, I bought a 3-pack on Amazon for [amazon_link asins='B01EV1LEIA' template='PriceLink' store='boingboing' marketplace='US' link_id='cce2d28e-dd60-4ee4-bfb4-6be4319d1402']. They really do work. Both the USB male plug and the micro plug can be inserted without regard to the orientation, like a USB C plug. There is no "right side up."
Why aren't all USB cables made this way?
