The great thing about iOS (and OS X) is that full screen zoom is trivial to enable and has a very simple shortcut: Settings > General > Accessibility > Zoom I set the zoom region to full screen. The three finger double tap is a good enough shortcut. On OS X I use the same feature with Ctrl+Scroll to zoom anywhere on the screen. You can even toggle whether pixel interpolation is used (great if you are checking artwork and want to keep the individual pixels crisp). I rely on these features, even though I have no trouble with my eyesight. They are wonderful and work everywhere.

The OS-wide accessibiliy zooming is just pixel zooming, though. When I zoom the viewport in a browser, it re-renders the fonts and may even show more detail on the images (assuming the images were sized down to begin with). I also still have the toolbars at the top and bottom of the screen. I agree with you on the triple-finger tap/Ctrl+Scroll options. I use them all the time to check things out, but I still want my iOS web pages to be pinch-able no matter what the website wants

  That's right. A designer who uses `user-scalable: no` is consciously taking that interaction away from you. And in general the result is sub-par, web apps which limit the viewport feel cheap and tacky. It's a useful feature — mainly for apps which render say, an "About" page using a web view but want to make it look like a regular app page.

    It's a useful feature that necessitates slower response to taps. One has to pick one or the other. If you write your css to support dynamic type (in the case of iOS); zooming becomes less valuable as an accessibility feature.

No, it isn't because my original iPad (a.k.a. worst ripoff of the decade) is tethered to iOS 5 and can barely do anything. In fact, the fancier web sites that try to "help" me are now more prone to crashing the browser entirely.
