Just bought my 3 Room on the Broom,Winnie's Amazing Pumpkin and The Owl who Was Afraid of the Dark(lovely illustrations) 3 for 2 at Waterstones. All 3 are super books but the CD Rom in Room on the Broom is worth buying just for that alone.
It has a showing of the story with the words highlighted as it's read. It also has a really good book maker where you can choose pics,words and even your own text. It's got 2 games which are really good and simple just using the arrow keys. One is to collect ingredients for a spell whilst dodging the dragon. It's also got things to make and print(not looked at all) but my lot are excited about the witch/dragon snakes and ladders game in particular. Think there is a theatre to make and posters to print.
It runs well and is really simple to use and kid friendly. Highly recommend it.
