I do not always use the full width of my screen for the browser, so I can have a small chat window, news, or whatever else next to it on screen. Thus, what I'm seeing in the browser window would be similar, though just not as much at the same level of clarity, as what is seen on the Pixel. I'm sure that's apparent to everyone though. I was going to assume that doing the same on a retina version of this Macbook (mine is older...2011) would be quite similar to the Pixel. Once again though using less of the screen.
On the iMac I never use the full screen for anything other than video. It is just too big for that to be comfortable.
