Again, I think the Cambridge is a great unit for those that are not highly computer savvy. I also looked at the Olive units (did not listen though) and from what I recall reading, they too, are quite simple to use without requiring too much computer savvy. I cannot comment any more than what I have read on the Olive systems in terms of sound quality (good, bad or otherwise).
I can tell you that my Cambridge is used by everybody in the family, from my wife, my 11 year old son and with his help, my 7 year old daughter. Which may not say much as kids now days are more computer savvy than most of us.
