I run a food blog and I have people sending recipes to me for testing, sometimes as a single sheet, sometimes as an ebook, but always a number of different file types, pdf, epub etc I'm considering getting myself a tablet to view them on, as printing them out is a bit of a pain. Is there a decent tab out there, very basic that I can view everything on? I've no interest in moving from paper books to tablet format for my other reading, and it doesn't need any other fancy apps or features at all. I just need to be able to plug it in to my mac and drag the files on. Any suggestions? Thanks.
