I'll throw something else into the mix. I have a Cannon Powershot Digital with an SD memory card, but... and here is where it gets different.
One of the hot trends in digital photography now is to geotag your images. Meaning if you're out and about, when you take a picture with a camera that can geotag, your location information is embedded in your picture data. Purely by accident I found out that my iPhone does this, very cool.
So we were in the market for a new digital camera so of course I wanted one that will geotag. At the time only a couple of companies were making them and they were pretty pricey. So I investigated further and found an SD card that not only geotags your photos, but also wirelessly uploads them to a "cloud" then download them to your computer. It's an awful lot to explain here, so here is the link to the SD Card called the Eye Fi that will work with any camera that takes an SD memory card, it's all explained. If you're interested make sure you read carefully because there are different cards that do different things.

I got mine from the Apple Store, but I now see that they are available at Best Buy. The photo shows what happens when iPhoto geotags my pictures. It will place a pin on the map, if I click on a particular pin, it will show me the photos associated with that pin. I'm not sure what photo program this will work with on a PC, I'll leave that investigating up to you, but if you have a MAC and iPhoto, you're all set already.
