Where does it say Metroid Prime Hunters comes free with every DS??? The Nintendo site doesn't say that.
Perhaps they're selling bundles, for let's say $170 or something.
I'm really happy that PictoChat is embedded in the hardware! Now it will be used.
Null, I like the idea of communicating with people close to you. Let's say you're in a train and some other dude enters. You immediately get a message. You can contact him (practicly anonymous) and ask him to play a game together.

Sounds great to me!!!!
And it will be fun for friends.
Edit: the latest thing I've read on C-E (

) is that you get a demo of MPH.
The DS also has alarm functions. The full fact sheet is pretty neat.
