That should save some time, your SD-card up-loading while you are still waiting for the elevator to get to your room or waiting around at the airport!
Announced just yesterday we have our review of a production Eye-Fi card. The Eye-Fi card is a two gigabyte SD card with built-in WiFi capability. The provided Eye-Fi Manager software allows you to associate the card with wireless access points and choose to have images automatically uploaded to your computer and also any one of seventeen online photo sharing sites including Facebook, Flickr, Fotki and Picasa. Once setup you can put the card into (virtually) any camera supporting SD and have your images automatically upload. We've had an Eye-Fi card for a few days now and have had a good opportunity to test it. So dive in to our review to see how the Eye-Fi card shapes up.
