My friend Tom Mighell has a wonderful book for newbie iPad-using-lawyers called iPad in One Hour for Lawyers, which is available from the ABA in print ($35), or from the Apple iBookstore as an e-book ($18). Seems like the e-book is the obvious choice, especially when you factor in the price.Tom walks you through how to set up your iPad to get the basic lawyer stuff done, and it truly will only take you an hour or so. Every lawyer who gets an iPad for the first time should get this book.
P.S. If you want a better practice, start using the 80/20 Principle.
Thanks!! I just got my iPad (haven't even had time to play with it). I got it because I've seen alot of colleagues use it in the courtroom, but I wasn't sure exactly how to use it to make me more efficient.
