I was given a multi-function camera for my birthday, so I've been playing with it. So far, it seems adequate for my needs and fairly simple to use.

It comes with 16 mb built in, but you can add either SD or MMC cards for up to 2 gb additional storage.

Is there any reason why I should choose one over the other? I have no other devices (as yet) that uses these things, so it's pretty much up in the air right now.

Any advice appreciated.
