(Note: this book was updated 5/22/2010 to include dozens of more tips and tricks!), as well as an added appendix full of dozens of apps to check out and a new chapter all about iPad Pages, Numbers, and Keynote.
History will decide if the iPad is as revolutionary as some people think. What’s important is you have yours, and now it’s time to tweak it with Apps galore!
The point of this book is to show you how to get the most out of your new investment, and not just to repeat ever
