So, Nintendo has announced the 3DS, the newest version of the DS, their line of hand-held gaming systems. But this isn't just for video games.
The '3' in 3DS stands for 3D. This means that the system will be able to do 3D for games. Even better (especially for me, since I already wear normal glasses), the 3DS will not require special glasses to see the 3D effects, and will be able to transition between 3D and 2D.
That isn't all it can do in 3D. From what I've seen, it will also do 3D movies. So now you have games, and movies, which of course can both be 2D and 3D.
And since it is a DS, it will be compatible with the older DS games. They will not have 3D, but you will be able to play them. And one of those 'games' is 100 Classic Books, which makes the DS basically an e-reader (with a limited number of books, but that is fixable). And it will probably have access to the internet at least through Wi-Fi, like the DSi.
So now the feature list is a bit bigger: 2D and 3D games and movies, books, internet. All in a device you can fit in a pocket. But wait, there's more. Since it does video, it wouldn't be hard to do music as well. So you have movies, books, games, internet, and music all rolled into one device. This would be nice for people who are currently carrying 2-3 devices, plus a phone, for this. The interface might not be the best for some of them, but the number of roles, as well as the 3D aspect, I think would allow it to be very successful.
