random i know but i was helping my friend get a pdf ebook on her ipod.
to go from a pdf to txt if you cant with adobe because its protected or whatever maybe you dont have adobe and maybe you dont want to download some stupid thing that wont work
register a gmail account send yourself an email with the pdf as an attachement then open the email and view the attached file as html, and then copy and paste/save as a txt.
if it wont display because its a lengthy pdf get pdfsplit (free trial at their site use google or even better use well nm) and split it into a few parts.
