There's one more lightweight, text-based browser to add to the list and that's Elinks: A Full-Featured Text WWW Browser.
And of course in recent Emacs versions, there's always this command (which gives me a chuckle when I invoke it):
M-x ewwThat's the mode for browsing the web and it's quite feature-rich but still very fast. It's what I used to post this response, BTW.
