Yes. This was not a typo. Some folks developed a "memory card" which is in fact a wireless adaptor and it is called Eye-Fi.

Basically, it is a 2GB SD card that actually stores photos taken from your digital camera. But it has an added functionality: It integrates WiFi technology to your camera.

You just need to configure your wireless router/access point to accept wireless transmissions from this baby, and if you are shooting pictures in wireless range, they are automatically uploaded to your computer. It also includes a service that allows you to also send the pictures to sites such as Flickr and others. What's more? You can take out the card and replug it, and the photos will still be there, and they will still be uploaded when re-plugged.

That's a pretty sweet device IMHO, except for its $100 tag. If you shoot loads of pictures, and don't want to keep plugging in a cable, this is for you.
