David Pogue recently unveiled Mac OS X Leopard: The Missing Manual, the latest book in his lineup of humor-injected technical manuals. Pogue says that the book is designed for advanced-beginners and intermediate users, but miniature sidebars called "Up to Speed" will provide background information to first time users. There are also shaded sidebar tips called "Power Users Clinic" seeded throughout the book, designed to give Mac veterans tips and tricks that even they perhaps did not know about. O'Reilly Press is currently shipping Mac OS X Leopard: The Missing Manual, and it sells for $35.

"With the Mac's market share at 8 percent and climbing, it's a serious player with a serious following, especially among Windows switchers and first-timers," says Pogue. "The world needs a single, complete, reliable resource to be the Leopard bible."

Pogue says that Mac OS X Leopard: The Missing Manual is dedicated to sorting out the fantastic from the average in terms of new features from 10.4 Tiger.
