I use Apple's Hide My Email to sign up on websites where I previously would have used a Temp-Mail-Service such as 10MinuteMail. These are websites I want to use anonymously (Hackernews for example). It's more convenient and they give you the option to reactivate disabled aliases later (useful if you need password reset). I don't think they made it to replace your primary email, although you could use it that way.
