While it's pretty impressive that a root vegetable can handle an entire operating system, it won't help you get your computer up and running. Since it's based off of Linux, it has the ability to boot on pretty much anything, from a USB drive to a potato. It is currently the most popular Linux distribution and has a dedicated community that's actively working to make it smoother, faster, and more secure.
Ubuntu doesn't get a lot of love compared to powerhouses like Windows and Mac OS X, but those who do use it are often fans for life.
If you've ever wiped your computer without having a proper backup of your operating system, or just wanted to cause some havoc online, chances are you've had to rely on Linux to help you out, specifically the Ubuntu distro.
