Fast and lightweight, but fully functional. Easy to run, easy to install, easy to use. Perfect for a beginner. A vast and friendly user community. Highly customizeable.
Cons: Somewhat unstable: might crash if the user experiments too much. Always runs as root (not necessarily a disadvantage). Not as popular as other distros, so ready solutions are harder to come by.
Simple writing system. Pronounciation is easy for non-English speakers. Reasonably challenging. Sighnificantly broadens career opportunities. Less popular, specialists are in great demand
Cons: Very difficult grammar. Pronounciation very difficult for English speakers. Requires time and diligence to master. Not similar to other languages (except Japanese), thus harder to learn
