Pembo,
It's been around for quite a while. I used it often when I was teaching elementary school 15 years ago. I think your choice depends on your goal -- silly fun, relating to a particular topic or interest, more reading oriented (Cricket) vs. more photo oriented (Ranger Rick), etc. Good luck with this. It's a fun choice to have to make - there are so many options. How about a trip to the children's section of the library to see what your DS gravitates toward????
