If the 3DS wants to survive, it has to:
1) Have USB connection for the files that it can play, such as...
2).... MP3 files and...
3).... MP4 files, both of which will require....
4) ....compatibility with at LEAST 64 Gigabyte Flash Cards (which will be available by the middle of 2011).
5) Now that you have a
Fricking 3D Camera, why not have
Video Taking capabilities too?
6) Oh, and applications that allow you to draw, write stuff and read PDFs would be nice too. Not to mention Edit the Photos (and Videos :P) if you have taken any.
They HAVE a Touch screen and a
THREE D CAMERA AND SCREEN now, there's no excuse they can't at least TRY the above.
