Some can say that the iPad transcends the need for a user manual. While I want to agree, iPad: The Missing Manual is a great book for iPad users looking for an overall reference or those that want to fill in some of their knowledge gaps and learn something new that they may have missed in their tinkering with the tablet.
The book is a good soup to nuts introduction to the iPad with the first three chapters covering the basics of iPad setup, a tour of the iPad’s major parts, and the basics of interacting with the iPad. Chapter 3 is a must read for new iPad users who may not be familiar with finger moves and gestures. More experienced iPad users should get something out the chapter’s coverage of using voice and using keyboards for interaction and inputting information.
