It's lightweight, open source & it has many customization options (like customizing desktop). I'm using this to learn linux/unix systems so that makes me happy about its features for learning purposes as well! Nothing much at all actually i guess!! If you want something very easy then go with other distros but if your looking out for anything more than just ease of use or simple things like file management etc - look no further. This one will be perfect choice in terms of performance also because it uses less resources compared even windows 7 which was always considered heavy weight OS till now!! So my point here being there are some light waight alternatives too when we compare them side by SIDE not only from an end result perspective!
