I think Nintendo needs to make GBA-type cartridges with a flash-drive (It would have something like a gigabyte of memory), which would let you transfer songs, videos, pictures, and small games to and from your computer. You could stick the cartridge into a little stand which would, by USB or wirelessly, be hooked up to your computer and would let you store it w/ anything you want.
If a tree falls in the woods, do all the others laugh at it?
