When I bought Apple iPad Camera Connection Kit at Apple Store Yesterday, I also purchased this GRIFFIN USB Mini-Cable Kit.
Just in case, I'm always bringing micro USB cable and USB memory in my small pocket at my right side of Jeans. But this micro USB cable is really too small then difficult to use sometimes. This Griffin's one is just fit in my small pocket and seems better quality than tiny one. It seems better for a pocket battery type of accessory as well.
