Ripping CDs IMHO is a non issue. Even the new Minis don't have an optical drive anymore.
As for back ups, I agree that it could be an issue.
But the Sony does provide an app for you to make back ups of the music library. I personally like the ability of the Sony to run with local music files rather than trying to retrieve it off a network device.
FWIW I don't own the Sony but I see it as a way to get the computer out of computer audio. I too run a Mac Mini with JRiver and iTunes at the moment.
