I think some of you are missing the point here.
Sure, I agree the 3D iPod prediction might be a bit off, though it'll likely happen in the future, but you're seriously underestimating the threat Apple poses to Nintendo.
You're all mentioning core titles on the iPhone, and yes, while Street Fighter IV isn't going to play as well without buttons, far from it, it's the games and software that appeal to the wider audience that post a threat. Remember, Iwata said Apple is Nintendo's enemy of the future.
The point is I can see most casual gamers being happy playing games (good games, I might add) like Cut the Rope HD, Angry Birds, Bit.Trip Beat, Infinity Blade, Puzzle Quest 2, Telltale's adventure games and the like for 59p to �£6-ish each and be perfectly happy with that.
Don't forget the original DS was so successful because it had games that appeal to everyone, making it truly mainstream. The PSP hasn't had that success because of the obvious reasons (UMD slow loading times, poor battery life, dodgy controls, software library only now appealing to the Japanse audience).
The point is, Apple may very well eat into Nintendo's share of the expanded audience market if Nintendo and third parties don't start making games to reel them in. I imagine if 3DSWare is done right it'll rival the App Store too, which should help Nintendo a fair bit with those used to buying games for �£1.19 on the iDevices. Of course the 3DS does already have a few features to get that expanded audience onboard: 3D movies, augmented reality, 3D photos and the like. But we shouldn't underestimate the threat Apple are to the 3DS. They are getting people who don't usually play games playing games, just like Nintendo are. Of course they are doing it through WiiWare-style titles which also have a low price level instead of the �£30 for a DS game.
The unfortunate thing is whether the average person values the length and depth of a DS/3DS game to buy them over an App Store game on their iDevice. Of course this still holds true today with games like Layton doing exceptionally well but who knows what it'll be like when a new platform launches, where people will have to spend money buying the console first before the games.
