The problem with either of those cables is that one would still need another adapter piece to connect to devices. However, if it works for data, the micro-to-mini adapter is the most ideal at this point. I've only seen them described in reference to charging, though.

Why do those Micro-A cables to full-size A-plug even exist in retail? Both ends are for host devices! They serve no purpose that a (soon to be commonplace) Micro-B cable does not fulfill.
