What I find interesting about what you're doing is how you're approaching this. A new linux user in 2010, you're looking at stuff like a windows user sort of. You're talking about toolbars and widgets, stuff I have no idea how to do.
Linux desktop users from years ago, like myself, are still using the command line all the time. I've got a terminal window open almost all the time. I edit my html at the command line, copy files that way, a whole lot of stuff. I suspect you're doing these types of things through the gui. You certainly have a much better grip on the desktop than I do. My desktop is pretty much unmodified from the default install.
Interesting how that's changed.
