Special thanks to everyone at Apple who helped us turn this book around so quickly: Katie Cotton, Natalie Kerris, Natalie Harrison, Teresa Brewer, Janette Barrios, Keri Walker, Jennifer Bowcock, and everyone else who lent a hand from the mothership out in Cupertino. We couldn't have done it without you.

Big-time thanks to the gang at Wiley: Bob "Can't you work any faster?" Woerner, Rebecca Huehls, John Edwards, Andy "The Boss" Cummings, and our technical editor Dennis R. Cohen, who did a rocking job in record time as always. Finally, thanks to everyone at Wiley we don't know by name. If you helped with this project in any way, you have our everlasting thanks.

Ed adds: Thanks to my agent Matt Wagner for again turning me into a For Dummies author. Matt had the right instincts to push this book, even back when we were calling it Project X For Dummies. I'd also like to thank Jim Henderson, Geri Tucker, and Nancy Blair, and all my USA TODAY friends and colleagues for your continuing support and encouragement of such projects. Most of all, thanks to my loving family for understanding my nightly (and weekend) disappearances as we raced to get this project completed on time. You are quite simply the greatest.

And Bob says: Extra special thanks to my agent, Carole "Swifty" Jelen. She has guided my writing career for more than 20 years and she's still the best in the business. Here's to 20 more years of friendship and success.
