What I like:
- The installer is now really professional looking. Just add the Flash plugin somewhere in there and it will be ready for the masses.
 - The About box is really nice. It's a good thing to have used Steven Garrity as "brand coordinator".
 
Some minor gripes:
- The installer doesn't have the new logo, but the Mozilla dinosaur. Who said something about brand identity?
 - Still using the Qute sickle as throbber icon... what about using the fox now?
