I bought a PC from Madtux pre-installed with Vector Linux 5.8 SOHO for my 15 year old daughter last month. She is not at all interested in computers beyond the value of the immediate usage. She has none of her fathers interest in computers and technology. She is, however a convert to linux. She found it easier to use than windows and much to my surprise has learned how to customize her experience with linux without any help from dad.
In my humble opinion that is the true test of any OS. Vector Linux passed with flying colors!
