Source & rest of article.Out of the box, Ubuntu and Linux Mint look very different. From colors and icons to the placement of launchers themselves, each distro offers a completely unique experience when compared to one another.
But perhaps the biggest difference between the two distributions is each one's overall direction. Ubuntu is attempting to become a jack of all trades, offering Ubuntu experiences for the desktop, Ubuntu TV and smartphones. Linux Mint on the other hand, is quite content in keeping its original mission of providing a great desktop experience.
For example, Mint offers a typical desktop experience when it comes to browsing your menu, locating installed software and browsing files. Ubuntu however, has sweetened the experience a bit by allowing the Unity desktop to provide a dock for frequently used application, in addition to being able to locate and launch software using the Unity Dash. The idea, of course, is that the Ubuntu approach is easier to navigate. Personally, I tend to disagree, but others seem to enjoy Ubuntu's approach.
