This is my frank opinion. I have the iPad camera connection kit. But it is troublesome. This 3-in-1 camera connection kit is really what Apple should be looking at.
Now, you have camera connection, SD and MicroSD card slot all in one small dongle. It comes in White and Black and it ready for pre-order at USD29.90. BTW, this is unofficial kit from Apple.
