Pointless.
The 3ds is currently the best selling console and it seems that it will continue to be for a long time. The 2Ds is just a cheaper option to play its games without the 3d effect, just like the DSLite was a cheaper option to play DS games without the internet connection.
I do believe that the 2ds is meant not only to small children, but also as a way to improve 3ds sales in other regions, since it will be a lot cheaper than a regular one
