I'd second the Missing Manual Suggestion. David Pogue is great. He's also got a boook called Switching to the Mac. I got frustrated trying to create a book with Appple, because they tell you next to nothing, but Pogue's iphoto 6 book was invaluable there, too. While I was writing this, Apple just sent me an e-mail about their new 24-inch iMac. The beat goes on.
