I disagree, I have a averagely-sized phone and greatly appreciate the fact that the browser bar is at the bottom, since there's basically no way for me to reach the top of the phone without changing my grip.

It seems to me that it's only possible to reach the top (and even then just the top right, not the entire top part) if your phone is less than 3.5" tall.

Hmm. Personally I dislike the visual noise of the address bar having to move for the keyboard to load in. If I'm not mistaken, the address bar also slides off screen when you're scrolling through a page, but because it's at the bottom of the screen it goes in the opposite direction of your scroll (as you go down the page), and I find that jarring.

Maybe my hands are unusually large or something, but back in the glorious days of the Nexus 4, I was able to reach the top left corner (as a right hander) quite easily. That phone was 4.7 in diagonally, with a fairly generous bezel that GSMArena says makes it 5.9 inches in physical dimensions. (I'd argue this is misleading, because the top left corner of the screen is easier to reach than the top left corner of the phone.)

In comparison, my current phone (Moto X4), which was the smallest phone I could find at a reasonable price, is much heavier, has 6.5 inch diag physical dimensions, and is made of slick metal. I struggle to use it one handed to the point where I start to see the appeal of relocating the address bar.
