I am not very tech savvy and this book covers all the details of how I can really use my blackberry for e-mail, calendar, and much more. It showed me how to download applications and really get the max of out my blackberry.
I got an e-Book version, but I think I will buy the actual book when it is out. I need to read a few chapters again to decide which applications I should download from the Blackberry AppWorld. The book describes many of them and will help me pick the right ones for me.
