I'm very new to the iPad and wish to use it for reading books. The more I tried simple solutions like using iTunes or iPad Magic to copy books from my Windows computer to the iPad, the more confused I got. Additionally, I've tried to find a universal reader, read descriptions and reviews, but am still uncertain about the best product and how to accomplish this seemingly straight-forward task of using the iPad as a flexible reader. The ideal solution would be one product that would allow me to read PDFs, epub and mobi files. Additionally, I would like the app to be open, meaning that it would read any PDF, epub or mobi book regardless of whether it was purchased or free. I have no problem paying for the best apps to do this, which would include the ability to have all books, regardless of format, in one place, recognized by the iPad reader as well as whatever product I wind up using to synchronize between my Windows computer and the iPad, whether it's iTunes, iPad Magic, Calibre or something else. So there you have it. Thanks in advance for the assistance.
