Galeon's got a full-screen mode. On my laptop, with a 1024x768 display, it's nice to be able to devote the entire display to content, though this varies with the type of content -- for pure-text sites, I find that a width of 700-800 pixels works better (long lines are hard to scan). It's also possible to toggle display of toolbars -- menus, toolbar, bookmarks bar, status line. Even small amounts of extra space, particularly vertical space, translate to a large increase in apparent (or real) real estate.
I first noticed this many years ago with Win95. The company president was using MS Word on her machine and had managed to get a bunch of toolbars installed. She was running 800x600 resolution, with a boatload of toolbars, plus the window decorations, Office Shortcuts bar (top) and Start bar (bottom) of screen, plus rulers and Fnord knows what. Her practical viewable workspace for the document was maybe a dozen lines of text. This is progress? You've got more viewable work on an 80x24 console. Me, I like to work in a terminal with at least 60 lines, preferably 79-80. Yet another reason to despise WIMP GUIs....
