HELP ME! MY GUIDE TO THE IPAD AIR2 BY CHARLES HUGHES

I bought this book HELP ME! MY GUIDE TO THE IPAD AIR 2 BY CHARLES HUGHES because I just DID buy a new ipad air 2 and wanted some guidance on the newer version of ipad.  I was rather disappointed in it.  This book was more welcome to the Ipad book not anything new that I did not know having the first generation of Ipad.  In other words this book is ok if you have never owned an Ipad but if you have its pretty much the same information .
