I got my grand-father (who is an early-adopter type of person but not tech savy) on Linux (latest LTS Ubuntu) about three years ago. Telling him he won't have to bother about antivirus and making sure it had applications and drivers for all his uses (chess, emails, internet navigation, picture and video) was the only things needed. So far he is really happy it and loves that you can get a high contrast user interface with large font size out of the box.
