Eye-Fi Card - Wireless Memory Card

The Eye-Fi Card is a wireless memory card. It automatically uploads pictures from your digital camera to your PC or Mac and to your favorite photo sharing, printing, blogging or social networking site. No cables, no waiting, no hassles.
I was in disbelief when I was first told about this little gadget because it is such a small wireless device. I haven't tried it myself, but it would be pretty cool that I don't need to worry about the upload process. I imagine that when the location coordinates are stamped into EXIF information of the pictures, uploading and geocoding pictures on Flickr, Picasa, or other map-based photo services will be so easy.
