I seem to be in an overwhelmed minority. When I 'zoom', I seldom, if ever, want the images to enlarge, or the layout as a whole to get bigger. I want an increase in text size. Period. Full stop.
I have always thought that Firefox got it right from the git-go, and IE's failure to enlarge pixel defined font sizes was an error. I do appreciate the option to truly zoom in, but in my browsers, text-only is the default.
