Would like to know before I purchase 2nd generation Ipod touch if I will be able to access and use pdf files easily. I work for the Railroad & would like to download rule books onto touch. I'm tired of carrying all those heavy rule books. A lot of guys have palm pilots which work well for them. I know a lot of them use isalo (sp?). My question is: will I be able to touch on something in the table of contents and go directly to that section, or will I have to page through until I find the section I am looking for? Thanks.
