From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I'll add upon what others have said here, for me the main downside is the size they take on disk since they don't really share dependencies (they do but not as efficiently as native or nix packages) so they take a lot of room and take a while to update. Otherwise they're amazing IMO and you should use them! :)
