I use iPad Air to read tons of technical papers, books, and magazines - and no - phone - just will not do for it, let alone lugging stacks of paper. I occasionally read fiction on an iPhone 6, but anything that has charts, formulae, source code, or good typography and photos (as in magazine articles) is a pain to read on a phone. I also watch TV shows, videos and movies on iPad when I feel like doing it on a couch, as laptop is a bit too heavy and bulky and I just do not bother buying a TV set.
