Me too! Everyone says that they work in a CF card adapter, but I have tried two different adapters and none will fit into my Nikon D700 - they're all too thick and will not go into the camera.
They did fit into my Nikon D70, but the range was horrible. I couldn't be more than 20 feet away from my wireless router.
I can't believe they make this in just one card format!! Imagine if Lexmark and the others just made one kind of card - how silly would that be?
Eye-Fi - please get on board already and make other formats! I'm sure Sony users would love a memory stick version!
