What is up with this stuff? It's a GAME SYSTEM and that's what Nintendo wants it to be first and foremost. Not a do it all tablet, those are already everywhere. I guarantee you already have a smartphone, tablet, Blu-ray player, smart TV, maybe all of these with these apps already on them. There is no reason that you need ANOTHER portable device with them on it.
That being said, I'm sure they are in the works because people are complaining about them not being there for some strange reason. I already have like 8 devices in the house with this stuff, no real need for more.
