I have a buddy that is not very computer literate and loves his mac ( for what little he knows about it). He is a great chef and runs a successfull business just going to people's homes and cooking for them.
He needs to:
1) contact the person back if they have not been in touch for a while
2) keep track of simple things such as if the person likes garlic or not
3) KISS ( keep it super simple).
Yes he has a nice mac. Not sure if it is osx but it is a later mac.
