It's also possible to set a bookmark to something like javascript:document.querySelector('meta%5Bname=viewport%5D').setAttribute('content','width=device-width,initial-scale=1.0,maximum-scale=10.0,user-scalable=1'); To re-enable zoom. I get as annoyed as the the parent comment with sites that disable zooming not because of the act itself but the bad design and typography choices that seem to go along with it. Make text size and leading choices suitable for the device, set margins so that your text doesn't abut the absolute edge of the screen, and make sure links are large enough to tap reliably. If you feel you can't make those choices and want to include full site or text size links somewhere then they should be obvious and again big enough to tap.
