My wife has dozens of pdfs in iBooks on her iPad, which she downloaded from the Internet via Safari. She has a new iPod touch and would like all the same pdfs in iBooks on that device too. What are her options? Would an iTunes (PC) backup of her iPad include the pdfs, so that we could restore it to the iPod touch? The only option within iBooks seems to be mailing each file. Right now I've installed Dropbox on each device and I'm going through the painful process of mailing each pdf to myself, then opening each email on a PC and saving the attached pdf to her Dropbox account. Is there an easier way?
