Micro USB is and always has been pretty terrible. Granted, the USB port won't be used on this much, but still. The micro-usb nano looks pretty non-standard to me, I'd stick to something more mainstream. I'd get the blue 328 or the 328p. Pretty sure all mine are the 328 version, though IIRC the 328p is a little better in some what that I don't remember.
