In principle at least, there's no reason why having a larger proportion of your field of view covered by the screen ought to make things worse. If fullscreening a document is going to make it uncomfortable to read, well, don't do that then. Now in practise not being able to just fullscreen things can be awkward, but that's a software problem with current OS GUIs, not a hardware issue. https://hackernews.hn/item?id=8634121
