One thing to watch out for when getting digital cameras are the recording medium. There are two types.
Cards are squarish, about the size of a large postage stamp. They are usually marked SD or Secure Digital. There are many sizes down to microSD, which is as big as your fingernail, but narrower. They are by far the most popular.
Sticks are longer and a little wider. There are two sizes. These are found in Sony cameras.
The biggest difference I have seen is price. The Memory Sticks seem to have a $20 tax placed on them. I suspect this is a Sony tax. When buying a camera beware of this. Initially, you will buy a recording medium, because the cameras ship with “cards” so small you can’t even buy that size in the stores anymore. A Memory Stick camera adds $10-20 to this and then adds $10-20 per Stick on every future one. This is a little extravagant for me.
One last recomendation is to get a USB “card” reader for the camera. In case you are with family you can copy the pics to computer without the cable. Here’s one for $5.
