Nintendo 2DS - $148
iPhone 5C 16GB - $739
There's your reason why the 5C won't favour so much of a younger audience whereas the Nintendo 2DS will.
I'm not comparing the product on price, just the companies decision on design. A product that is a little more sturdy for a younger crowd.
The 2DS is meant for 3-4 year olds. The 5C will be for 8 and up.
