It has more then the 3D. It can do so much, I'd rather not list it myself. Seriously, read here: http://en.wikipedia.org/wiki/Nintendo_3DS
I read the features page.
Activity log? Yeah, that'll be used.
Augmented reality? That'll rarely be used, and will be terrible when it is.
Backward compatibility? That's pretty much expected from anything that replaces the one before it.
3DS Messaging Service? Nothing new here.
Virtual Console service? New to Nintendo's side of portables.
StreetPass and SpotPass Mode? Nothing exactly new there, either.
3-D video content? Yay, 3D gimmick!
Mii? Remember how many games they were in on the Wii and actually made a difference? Wasn't it none?
