I Spy Eye-Fi

Here's a holiday gift idea for the shutterbug in your family - the $99 EyeFi. Basically it's a 2GB SD memory card, with built in Wi-Fi. It can automatically upload the photos on your camera to your favorite photo sharing website, or even your computer, whenever it's in range of wireless internet.

With this it's easy to have your photos show up on a slidshow, as you're taking them. Works great at weddings.

While it may be a bit slow for serious photographers, for the casual user it's a super convenient (and completely wireless) way to share your pics on Flikr or Facebook before you even get home.
