Safari 4’s Full-Page Zoom
I must say that this discovery leaves me mightily impressed. There is just no comparison with how Safari 4 scales pages and how it used to be in previous versions of the browser, or how it still is with several other browsers.
I really like this feature as well. I have a 17 inch high res Macbook Pro and this feature is a god send. My only gripe is that Flash objects does not scale with all the other elements. So if you website has a few Flash objects, expect the zoom feature to mess up the formatting.
