Ximian comes with Galeon for a Web Browser. Galeon doesn't read any of your existing Mozilla information (by default, anyways; there may be some way to trick it into reading it). And Evolution uses Mozilla when you click on a link in an email.
I'm not sure about this Panel-Across-the-top-of-the-screen thing. I've spent way more time on it on the laptop and have moved some of the default thingies from the top bar down to the bottom bar where I like them.
The System->Personal Settings dialogue is a bit sparse. I am not entirely sure what is missing, except that I have the feeling that every time I go looking for something I don't find it there.
I'm not entirely sure that the SunFront key functionality is working properly on the Windows Menu key. The Windows key still won't permit itself to be bound to an action.
The installer is reasonably slick, but it took longer to install on the laptop than I expected (about two hours). There doesn't seem to be a way to run the install in an unattended manner, nor any way to integrate it into the existing Kickstart.
This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
