I have to say, that is a God awful design. I think part of the appeal of the 3DS/DS is that you can fold it in half and stick it in your pocket. This looks bigger than the Vita. The button placement also looks like it may become uncomfortable to hold after awhile. Why not just make a 3DS, with the same case, but without 3D? Or better yet, just tell your kids to turn the 3D off?
