This interactive book is used by my 3 year old boy, who likes it very much.
It's easy for me to get up and running for him and once the program starts hes immersed in all the different interactive features it offers. There's plenty of things to click and drag, a few puzzles and when you click on the words that are on screen an actor says the word, so not only will it develop his computer skills but also his reading, which I find very appealing.
I'm sure within time he will get bored of this and move on to something else (as all children do, of course) but in the near future this will help him with his reading skills if nothing else.
One slight problem I have found is when you exit the program back to Windows it can mess your icons around (if you use a different higher resolution than that used by the game) this is why I've only given the product 4 stars.
