Seriously, I tried to like Tag-Connect. I did like it before supporting a CM and a hardware team trying to use it (and lose the cables...). Now I just plain don't think it adds value over the alternatives. The header is three cents. Three. Cents. The cable is $39 (with legs, $34 without). That buys you over 1,000 headers and then you can use the free cables that come in the box with all the debug probes and live in the pile over there in the shop.
