Hi,
I almost exclusively read software development ebooks (e.g. from Manning.com), that's regular PDF documents with some graphics, etc. (200-1200 pages)
Currently I almost always print the documents in the company (which is cheaper - at least for me

- and quicker on my desk compared to the regular book)
1. Do I need to convert the PDF documents with those IREX devices? Or plain copy them onto an SD card?
2. Are there any keys to jump to the top of a document (e.g. index) and use hyperlinks in PDF? Can you bookmark pages/documents?
3. Would you recommend a touchscreen version or the cheaper variant of the reader for my purposes?
4. Any general problems with the IREX pdf viewer? Showstoppers?
Thank you!
