If you want to carry files on your Nintendo DS, the DS-Xtreme card looks like a neat solution for it.
The DS-Xtreme card connects directly to your PC via USB 2.0 and does not need any software. You can drag'n'drop files directly onto the integrated flash memory.
This is one of those accessories that is somewhat unofficial and not licensed from Nintendo. The group behind the card has launched a teaser flash site so far and promises to put the DS-X card on the market soon.
