The ease of setting up new servers and the fact that most of the services are pre-installed. I also like the fact that I don't have to install a lot of applications to get a functioning server. Although there are a lot of services to configure, this is a great way to get a server up and running quickly. There are several features that I dislike. For example, the fact that you have to reboot the server to log out. I also dislike that I can't have more than one instance of the same service installed on the system. The most important thing is that it is very easy to set up a new server even if you have no experience. I have been able to set up Linux servers for years and this one has really helped me a lot. I use it for my online portfolio.
