My Mac has a guest mode, but I never use it. Do you?

Every time I have guests at the house that want to use the computer for some reason. That's what it's for -- why not use it?

To answer your question, no. But my Mac does have more than one user account.

It would be nice if iOS would support multiple user accounts/profiles, especially for games - so when a user is "logged in" a game's saved progress would be tailored for that specific user.
