Servo is very similar in useability to lynx right now, if grandparent is interested in trying it out.
> Not only does Phoenix aim to match the featureset of Mozilla -- subtracting features deemed geeky and better offered as add-ons -- but it extends it. For example, it adds customizable toolbars and quicksearch in bookmarks and history. It will soon offer an add-on manager, a better wallet, and a new downloads sidebar pane.

Still didn't ever complete the suite, though; Thunderbird tackled email, Sunbird handled contacts. Good thing, too; Seamonkey was a pig on my pentium 133 w/32MB RAM. Played quake fine, but just couldn't handle Seamonkey. Phoenix got me extra life out of my ancient hardware.
Now I wonder if it would be worth making something similar in XUL...
