By "simple", they don't mean like Windows simple. They mean as in like Spartan simple. Once you're done installing Arch, for example, you're not dumped into a nice GUI on start up. In fact, there is no GUI installed. There isn't much of anything installed really. Or at least nothing a desktop user would care about. IT's all mostly server stuff. Same with Slackware and Frugalware (which is a mod of Slackware?). They all come with command-line utilities, making them technologically simple as well. Big GUI programs found in Ubuntu and Fedora are very complicated and bloated. They use a lot of system resources. These programs are very complicated in their coding (GTK is a ridiculous API. A simple "Hello World" box requires a ton of code). The reason Arch and friends are for intermediate/advanced users is because they take a fair amount of knowledge of Linux systems to maintain. But Arch and friends are also good for beginners who want to learn a lot about Linux systems very fast. Since all of them are barebones systems and require a ton of configuration, one can learn a lot from just configuring the system to his/her needs. To wrap up, if you're looking for simplicity on the user end, you don't want to look at Slackware or Arch. But if you're interested in learning how to maintain a Linux system, then Slackware and Arch are for you.
