You are also more than likely using Xfce 4.10 when using xubuntu.
There are many more window managers, some floating, some tiling and some both.
matthew-S206:/etc/update-manager % xfwm4 --version

There is also a distinction between a window manager and a desktop environment.
Have a read of this.
If you want to try something a bit different then try a tiling window manager as well such as awesome. It can actually be used as both a tiling and floating window manager.
matthew-S206:/etc/update-manager % apt-cache search ^awesome
awesome - highly configurable X window manager
awesome-extra - additional modules for awesome
You may want to add some more memory for the heavier window managers.
