As I see it, the 350ms delay was added to support zooming via double-tap. What I don't understand is why double-tap zooming is necessary when we have pinch-to-zoom? Can't zoom via double-tap be sacrificed for instant clicks and everyone is happy?

Double-tap zoom is meant to be "smart" about what it zooms to, automatically. So if you're looking at a page with multiple regions and double tap one of them it will try to zoom to show you that region. I use this far more than pinch-to-zoom.

You can use double-tap zooming with the hand you're holding the smartphone with, im using it more often than pinch to zoom.

Try double tap zooming on a paragraph in a body of text. It should automatically zoom so that the paragraph occupies the full screen width. That's a pretty nice feature to just give up.

Seems like you'd still need the 350ms delay (or some amount of delay) for pinch-to-zoom because the two fingers don't touch the screen simultaneously. The sensor reads the first finger's touch and the software has to wait to see if a second finger touch comes in before it decides if the first touch is a tap or the start of a pinch.

I also never understood why you'd double tap on a link or a button.

You might double tap near a button, to expand it and give yourself a larger target.

Fat fingers.
