almost exactly the same.
I think XI added a few new options that were not available in X but the interface, design suggestions etc. are all the same.
The book does a good job of using images to ilistrate concepts using data and also step by step follow along design processes (i think using the northwind db). I am also a visual learner and i found Brian's book easier to follow than mosty others i looked at.
I also recommend that once you get the basic concepts down about grouping and formulas, read as many posts as you can, create sandbox reports for yourself to try and replicate the issue and the solution(s) given. It is a great way to pick up different appoaches and skills that you will apply later.
