Not since Sony played with bluetooth in the Cybershot DSC-FX77 back in 2003 has anyone done anything much about digital camera wireless connectivity. The Eye-Fi is an SD card with built in Wi-Fi chipset that allows any SD compatable camera to become a Wi-Fi camera.
Once the Eye-Fi card detects the home Wi-Fi network it has been confidured for, it automatically copes the images to a host PC on the network or uploads them directly to a number of web services. These include Facebook, Gallery and Flickr plus sites offering to print out digital images like Snapfish, Sharpcast and Shutterfly.
