I heard it's actually surprisingly comfortable. But yeah, it doesn't fold and doesn't have 3D and that is pretty much the only thing that makes it different from the 3DS. The screens are smaller than those of the 3DS XL, but they're the same as with a regular 3DS. Considering money is the issue, I'm guessing the 3DS XL is out of the question anyway. While I would recommend the XL to anyone with enough money, the 2DS is a great alternative if you have less of it and don't care about the 3D.

I'd say, go for it! Get a 2DS, The system now has quite a large library of great games and whether you play them in 2D or 3D, they're really worth it. Just make sure you get a good protective case. I worry those screens might get scratched easily with no clamshell design.
