- Forum: iPhone
4'' iPhone 5 was already too big to hold and too small to read PDFs or EPUBs. But so is iPad. If you have multi-column PDFs (like some textbooks) text is going to be too small to read on 10'' iPad let alone iPhone. So I don't see the reason to go with giant phone. It doesn't make sense at all. I'd rather they work on wireless foldable screens that you can hook your phone to if you need larger screen in a pinch.
