For the few of you that actually bothered to click on the article link, the picture shows some kind of really short cord with a plug at the end...
I don't know what the hell that is but it cannot be the cord the article is about, because the cord MS is sending is just the cord that goes between the power brick and Surface Pro, so it doesn't have a plug.
Also worth noting that the article summary might lad you to believe this was about the current Surface Pro, but it's not - Surface Pro 3 and older. Even then it does not apply to a Surface Pro 3 you'd buy new from Microsoft now, they ship with fixed cables already. It doesn't affect the Surface Pro 4 at all.
?? the cord that goes from the Sp3 to the brick is permanently attached. That can only be replaced by swapping out the brick itself. The *other* cord is the one being replaced, as shown in the pic.
