My mother-in-law bought eye-fi cards for Christmas. It looks just like the standard SD card that goes into your camera to hold your pictures. Only this little gizmo has an antenna. It causes your pictures to automatically download onto your computer. Take pictures. Set the camera next to the computer. Watch your pictures come up on the screen. No wire. No leaving the card in the computer. Done.
I confess to not doing any of the set up although it is my understanding that it was pretty much a plug in and go process.
*Oh... I should make a disclaimer. I have no connection to Eye-Fi and they didn't ask for a review.
