Midori
Midori is an alternate browser for Linux based on WebKit and GTK+. One might consider running Midori/WebKit on the XO if one requires a (very) fast-launching, fast-loading browser with minimal dependencies. Arora, a WebKit browser that requires Qt, is also a good pick. How fast is fast, by the way? Midori's pretty much up two seconds from clicking its icon on Sugar's Desktop.

Installing Midori on XO
Easy enough - install Midori from the repository:
# su - # yum install midori
Sugarizing Midori
Try out Sugarize to give Midori an icon. When sug prompted for the command:
Enter the terminal command used to start the program. ie, "firefox" or "mplayer -f"
I used:
> midori &
If you need a nice icon for Sugar, try out this one: Image:Activity-midori.svg.
Adding more icons
If you launch Midori, you may notice that its toolbar is missing a few icons. We can use the Gnome icon theme to fill in the blanks.
Install the Gnome icon theme:
# su - # yum install gnome-icon-theme
Then edit the Sugar icon theme file so that it inherits from the Gnome theme:
# nano /usr/share/icons/sugar/index.theme
Add "Inherits=gnome" as a new line right under the "[Icon Theme]" heading. Now none of the icons will show the "missing image" icon.
Caveats
In my experience, Midori may freeze or display visual glitches upon loading some websites. I'd love to figure out why this is... Midori also seems to forget the preferences in-between launches. (Edit: Nevermind, it seems to be remembering them.)
