I still love Nintendo for not being like "the other two". Also once more the Treehouse stream proved that they had software up and running instead of the "playable" demos from Sony and Microsoft. You have to admire that they fearlessly showcase that stuff live.
Also would never have considered the 3DS to be a failure. Someone mentioned "mediocre" hardware earlier, but I'm sure that's based on specs rather than the function of the hardware. I love my 3DS and I feel it isn't mediocre hardware in any way at all. It does its job just fine.
