What Is This o2 Bluebook?

I have seen recently where o2 have brought out this Bluebook.





What is it and how does it work?





I am on a Tesco talk plan (UK) and very pleased with this.





Can or does anyone ever think that Tesco will follow this. After all Tesco does ride 'piggy back' on the o2 network.
