This is brilliant. 

Eye-Fi.

Here's how it works.

1. You get the Eye-Fi card. 
2. You plug the Eye-Fi SD card into your machine. 
3. Onboard software initializes the SD card. 
4. You put that card in your camera and you're done.

When you use it.

1. Take pictures.
2. The Eye-Fi card uploads the picture automatically to your computer.
1. You don't  have to connect any wires
2. you don't have to tell it
3. no buttons
4. it just does it
3. You can also tell it to automatically upload those photos to an online photo account of your choosing.
4. Sweet.

The only hitch is you need a wireless network.  I have Cat-5 all through my house so I would need to turn on my wireless router, but most people are wireless now I expect.

This is a brilliant implementation because it does not require you as a user to buy a new camera to get this automatic functionality.  All you need is to replace you SD card and you are good to go.

Great product design.
