a wireless memory card.
Why? So that you don't have to plug your camera into your computer, download the pictures and then upload them to whatever photo sharing site that you use.
After installing the Eye-fi software on your machine and configuring access points and the photo sharing site of your choice (Phanfare, Shutterfly, Picasa, Fotki, Smugmug, Flickr, Facebook), once you snap a photo it wirelessly and automatically uploads the picture for all to see.
Not bad, and at $99 for 2 gb, reasonably priced.
