I like that it's very easy to install and configure. It's lightweight, so you don't have to worry about running out of hard drive space during installation or configuration. Also, it comes with lots of applications included by default for your use. It also has an excellent community support and tutorials available online. I dislike that there isn't much in the way of advanced features. There are some things that you can do but they require learning new commands. I'm using it as a server OS for my home network. The main reason is because it's lightweight and runs quickly.
