Hmmm, I don't really know exactly how pdf works. But I have some pdf books that I read on my iPad, link does work on some of the pdf and some pdf doesn't work. I think it's all depend on how they made the pdf. I could be wrong, like I said I have no clue how pdf works. So far, iPad pdf reader, i used GoodReader, works very well.
Haha, good luck The current PDF reader in webOS does not even render all PDFs...
€dith: OK, just opened a PDF I created with LaTeX in my Dropbox and the links appear to be working. You mean the links in the table of content, right?
I tried GoodReader with no luck!
Oh, I forgot to say: I can not install apps in tha iPad nor in the Touch, I "must" use the PDF Reader that starts from the browser, that's because some PDFs are generated automatically (uhm, yep is a little work that I'm doing... )
