With this new release, comes a new green based desktop that has been heavily customized. The welcome screen has the option to open a chat room, forums or contribute to the system in other ways and acts as a good introduction to the OS.
One of the most obvious changes, aside from the theme differences, between Ubuntu and Mint is the new menu that they have put in place. Personally, I prefer this menu style over the existing Gnome default and find it both easy to navigate and well organized. Hovering over an option opens its submenu and all of the main apps are easily accessible. Of course, if this isn't for you, it can be removed and replaced with the Gnome defaults with minimal effort.
Just like Ubuntu 9.10 brought about a revised software manager (see our Ubuntu 9.10 Review) so does Linux Mint. They have taken it one step further, however, by introducing voting and popularity to the software manager.
