I was just browsing around IGN when I noticed this picture of the DS cartridges.
I noticed they look amazingly similar to certain types of SD and SmartMedia cards and the like. I wonder if there is any chance Nintendo will make it so it would be able to read them...that could open up a whole slew of possibilites. For instance, watching MPEG movies or maybe even listening to music. It would compete more directly with the PSP if I did something simple like that. But I disgress, Nintendo has never been about things like that anyways, and it would REALLY shock me if they did something like that.
