You do realise that a microUSB is more hard wearing than a standard size port.

There was talk on mating cycles on IRC recently.

If you charge your device once a day; a microUSB port has a life of ~27 years, a miniUSB is ~11 years and a standard USB is ~4 years.

Since you now have a USB port sticking out, it maybe worth considering a DC power connection too, to take the load off the USB.
