As near as I can tell, almost every kid goes through an intense dinosaur phase, and for some adults, the fascination remains for decades. Even years after the movie "Jurassic Park" brought dinos to life, I would still eat up all the dinosaur documentary shows I could find, like "Walking With Dinosaurs." When I saw Inside the World of Dinosaurs as an app made specifically for the iPad, I was interested. When I saw that it was narrated by Stephen Fry, the UK actor, comedian and writer, I bought it.
