The new Nintendo 2DS system gives you all the features of the Nintendo 3DS and Nintendo 3DS XL, minus 3D viewing.
Nintendo should continue making new gaming systems minus 3D viewing. 3D technology as it is implemented today in gaming systems or TVs is not good for your eyes, especially eyes of younger kids.
One note: I don’t agree with those who believe single-purpose devices have no future.
Multi-purpose devices like the iPhone is eminently convenient, but if a better mobile OS and app platform comes around with all the apps we’re used to there’s no reason to stay with a particular platform. The experience of using Twitter is largely the same whether it’s on iOS, Android, or Windows Phone. I’m eagerly waiting for Sony’s ‘Honami’ smartphone and if the rumors turn out to be true I will be jumping ship.
When you want to play Mario you associate that desire with a Nintendo DS or a Wii. For Nintendo that one-to-one association is a good thing.
Update: Wait a second. The Nintendo 2DS is not foldable like the others? Not good.
