Adapter USB worked fine with a compact flash adapter plugged in, and card in it Why not make more adapters that could take compact flash or different cards not just smart digital. There are more than one type of camera card.
This is a must if you intend to take your iPad along with your digital camera. The pictures transferred from my SD card into the iPad very fast and the user interface is nice.
The USB connector did not work with my 3G iPhone. Not sure why but neither the iPhone nor the iPad recognized the other. Of course I changed the cable and made sure connections were tight. No luck. So, if you have a 3G iPhone, take a note of this issue.
Finally, the only complaint I have about this product is the way it's packaged. The two connectors come in a little tiny box and inside a plastic envelop that is open from both ends. Just exactly where does Apple think we are going to store this little, easily misplaced connectors? And why not combine both of them in a single connector?
