Pokémon X and Pokémon Y

Also: Nintendo, in case you forgot, the "2DS" already existed, it was called the "DS".

Yes, and DS's can't play 3DS games, which the 2DS can.

It's a cheaper version of the 3DS without the arguably useless 3D feature to bump up the price.

The design being for children is a bit of a stretch. It's design is not just useful for children, it's for everyone. pineapple the Nintendo DS/3DS and their shitty hinged top screen that breaks if you so much as fart near it.

It's a cheap alternative that fixes one of the biggest design flaws of the 3DS. yes, totally useless and without it's pros.
You didn't even mention any cons, just "I don't like the design, wah"
