The editorial makes a good point. I don't mind putting on the reading glasses when I sit down at my computer, but it's ridiculous to me to have to do that to look at my watch, or any device I'm using when I'm out and about. The glasses just aren't going to be nearby most of the time.
The opposite problem happens too often as well. I'll encounter applications obviously meant for a small screen, but I'm using them on a larger screen. The text is huge and quite readable, but much useful information is left out to save space or the text itself is clipped because the letters don't all fit so I don't see full names or other important information.
