RAID mirrors are a poor alternative to proper backups. They don't protect you from catastrophic file system problems, accidental deletion/corruption, flood, fire, theft, etc. I suppose for people on the road a lot, away from an IT staff, there is some benefit to having higher availability but in a world of <$500 laptops $30-$50 is significant.
