I received many requests for that and the last one just a couple of days ago from Greg Low in its useful review. I’m curious to see whether the sales of this book will continue also on Kindle. After 2 years this book is still continuing to sell as in the first months. The content is still fresh and will be good also with the next release of Analysis Services for developing multidimensional models. Thus, the only explanation is that the adoption of Analysis Services is still increasing and after the first cubes, readers look for more advanced content. We’ll see if Kindle will follow the same trend as the printed version!
