Is 4th edition of "iPad: The Missing Manual" the best one for an iPad2 owner?

Question on "iPad: The Missing Manual, 4th Edition", e-book. Described as for the iPad 3. I have an iPad2. Does 4th edition highlight parts that apply only to iPad3? Should I get 3rd edition instead? Appreciate answer today during your 1-day sale! Thanks.
