"It now takes something like 4 taps to get to the point where I can correct or otherwise edit the URL in my mobile browser (Safari)"

Just FYI, you can touch once in the URL bar to set focus to it (the whole URL will be selected), then touch and hold down on the keyboard (which will then act like a desktop touchpad) to move the cursor around to edit the URL.

I find this handy, though it took me a while to get used to it.
