I think i have to use Calibre to convert mobi files to ePub so iPad can read them but how do i copy the files across to iPad? Do i have to use iTunes or can i do it through Windows Explorer? When i plug iPad into a PC with a USB cable, it shows as a drive in Win Explorer but i can only see photos, no ebooks. The kindle has a folder called 'documents' that i can copy ebooks into but i can't see anything with iPad. Is it possible? Should i get a Samsung Galaxy tablet instead? Is Android easier than iOS for copying ebooks? Thanks.
