I'm quite determined at buying a new iPad in the following weeks, but I still have a few reservations, mainly related to its primary intended use: reading ebooks. I have a library of considerable size (i.e. tens of Gigabytes) of scientific books and articles in .pdf and .djvu formats. While using an iPad I'd like to be able to access at least a good portion of them - offline. My questions are: - What is the most convenient way to upload a library of this size to an iPad? We're talking about Gigabytes and thousands of files here and my internet upload rate is almost negligible so some common solutions involving cloud/Dropbox/mail attachments are out of the question for multiple reasons. Is it possible to transfer them without confining myself to a single application like GoodReader, iAnnotate, etc.? Is it possible for example to upload them to a "manager" app, where I can put them in folders or tag them, etc. and then choose the application I'd like to read/annotate with, preferrably without duplicating the document in the memory for each app? - I also have many .djvu files, (making up approx. 10% of the library). Is there an application which manages them along with .pdfs? It would be a pain, if I would have to use separate apps for the two filetypes. I know that I could, in principle, convert them to .pdf, but I'd really like to avoid doing that. On Android tablets these are almost non-issues AFAIK, as I could use a filemanager with some reading Apps; but as far as actual eBook reading is concerned they are not really a match to the 3rd Gen iPad's almost quadruple resolution and more fitting aspect ratio (at least that was my verdict after comparing them in practice at the stores). Also the annotation and management apps for the iPad look amazing. Thanks for the help!
