My drives are mostly gigabit nas drives. My only USB 3 drives are flash drives and a USB 3 card reader. My phone is a Galaxy S2 which uses the EU standard Micro USB charger. I don't need to get out more, and certainly don't need yet another USB connector.You aught to get out more Mike :=)
To have a micro form-factor USB3 connector that is backward compatible with a micro USB2, this double plug arrangement is a necessity. USB3 uses extra conductors, which are accommodated in the full size connector as an extra row of contacts deeper into the plug behind the normal USB2 contacts. You can't go deeper into a micro USB2, so you have to extend sideways - and to make it compatible with USB2 that means a double connector rather than a wider connector.I don't need to get out more, and certainly don't need yet another USB connector.
