Rich points out that we may have some progress on using micro-usb as a universal device connector. That would be awesome. I carry the most disastrous bag of wallwarts and cables now to keep everything going.
On the other hand, a new connector type for HDMI is coming. Sigh. The A/V connector/cable world remains a disaster.
Many good refs on the net for cable and connector types. Just discovered Hardware Book for instance.
