While I agree with this point, I also like my interfaces small. Because, since I don't click around on them, I don't like them taking up space.

I also use a mouse on my PC, so I'm fairly precise in case I want to use the icons. There's no need to blow them up, so my fat fingers wouldn't misclick on a tablet.

I like to code with two windows side by side, usually IDE + browser for docs, sometimes on a small screen. I'd rather have the extra pixels for the docs instead of random useless space around the IDE's widgets.
