Despite my laptop's display having 1440 horizontal pixels, I usually keep my web browser window around 900 pixels wide. I'd like it to be even narrower than that, but too many designers seem to assume it's a full 1024 and make their sites around 960 pixels wide. :) I do this for two reasons. One is that the remaining space on my screen is for other stuff. The other is that a lot of websites ignore the traditional typographic rules for line length, and even when those rules are followed, the principle of constraining the horizontal size (including things like navigation and sidebars) in order to reduce the necessary eye movement still applies.
