I think Nintendo should put some of their old handheld games on iOS and Android devices. Pokemon (Red, Blue, Yellow, Gold, Silver, Crystal) Zelda games, Mario games, etc... Now obviously they shouldn't put any games on these devices that can affect their hardware sales (unless these games are on their Virtual Console, not too familliar with Nintendo). But even if they are on the VC, not many people are going to buy these handhelds to buy these games.
Now to the Nintendo crowd, this may be a stupid idea. When you think about it, how many people own a Game Boy (Color, Advance) compared to the millions of people that own a smartphone. I could imagine them selling these games for $5 and making a good amount of money from it.
For me, I wouldn't buy a Game Boy Color to play a Mario game, but I would definitely purchase it if it was on these devices.
