I grew up with a Playstation. The only thing I am nostalgic for related to Nintendo is Super Mario Bros & Super Mario World.
I had a bad view of Nintendo in years past. Sometimes when I found a friend that had it, I played on their Nintendo 64. I never hated a controller quite as much, and I disliked every game I ever played for it. Even the bits of Ocarina of Time I was allowed to play. I thought they had been left in the dust by Sony at that point, even if my memories of playing their Super Nintendo were fond. The Wii's complete lack of interest in implementing a decent controller was not alluring to me at all. Motion control was implmented in games simply because the tool was there, even when a button would have been better.
That changed when I got my DSi. Mobile gaming had become The Last Homely House west of the Japanese Sea for japanese RPGs, platformers, everything that wasn't gritty, enfatuated with realistic graphics and guns. They still serviced niche markets because the games' development costs weren't through the roof. They could be more innovative than in the consoles because games didn't cost as much to make. They could be more old shool because they didn't need to make so much money back.
Now I have a 3DS. I've enjoyed playing Super Mario 3D Land and I'm playing The Ocarina of Time again. Only this time I'm enjoying it. The gyroscopical control is a lot better for aiming than the original analogue was (you still can use it though), the touch screen is used to add virtual buttons in addtion to the physical ones, with big enough icons that it's very comfortable to use.
So I like Nintendo more than I did when I was a kid. They're a good game developer and their portables have a pretty good library of games. Also, if I were to buy a console this generation it would likely be the Wii U.
