Nintendo has announced the small USB device that will allow any computer with internet access to become a wi-fi device for the Nintendo DS - handy for those who dosen't have a real wi-fi device itself, and for those who own several computers. You could bring one of those to your friend's home and play there, for example. And it needs no configuration whatsoever.

Unless I'm mistaken, this is the first PC device made by Nintendo!

So for those who own a Nintendo DS, expect a challenge real soon!

Also, I've seen some pics from an upcoming basketball game for the Nintendo DS, "Mario Basketball 3 on 3"... You control the ball by tapping on the touch screen, to bounce the ball, throw it, pass it... Very fun. Should be as fun as Mario Tennis.
