I should receive my iPad 2 in about 3 weeks. Although I am a veteran Mac user, the iPad 2 will be my first iOS device. So, I thought it might be prudent to buy a book/manual on using the iPad 2. I am not interested in a remedial book that spends a lot of time on things like: "how to turn it on", "where the buttons are located", etc. I suspect that I will be able to easily figure out all of the basics based on the owners' manual & my Mac experience. I am looking for a book/manual that deals with the less obvious so that I can get up to speed a.s.a.p. I would appreciate any recommendations. In fact, maybe it would be preferable to consult online resources (?). Thank you for your thoughts.
