Kids seem to really dig this

We got copies for all of our friends because kids really seem to like it--the coloring part is really, really well done, and they like having the history stuff read to them (unless they're old enough to read it, themselves).
Highly recommended.

I gave this toy to a friend of mine who has two children. I assumed that the oldest (about 4 years old) would enjoy it, and that's the case. However, rather to my and his surprise, it seems that the younger child (about 2) also enjoys it. The younger doesn't undestand all of what's going on, but he has figured out how to move things around on the touch screen.

Another nice aspect is that it seems very well built, in terms of holding up to abuse. Several times it's been treated roughly enough that my friend assumed it would break, but that hasn't been the case.

My 7 and 8 year old kids love this, but I do think it can be used and enjoyed by much younger children.  4+ sounds about right.
