I'm about to pick up a refurb iPod touch and enter the world of the app store for the first time, but I'm curious as to whether anyone ever made a dedicated PDF reader app? I know you can email them to yourself, and read the attachment. But I understand that Stanza (free) will open PDFs, as will Papers ($14.99... hmmm) and Reddle ($4.99), which also opens MS Word, Excel and Powerpoint files. Any recommendations? I intend to use the touch as an eBook reader, and I have about 400 PDFs I want to load up on it!
