I think the Windsor wives (Sarah, Diana and Sophie to a lesser degree) have all lowered the standards of their titles in general and that includes Camilla, imho, even though she's been shoved down the throats of the Brits and the Commonwealth as the great love Prince Charles. I still wonder if they'll make it to King and Queen, though. QEII seems to be plotting for her grandson, William, to succeed her.
As far as Andrew, yes I hope he finds someone who makes him happy and that happiness probably would have to mean that that woman can fit into royal life and be acceptable to his family. Is that so hard? Prince Frederik has done it in Mary and Prince William has shown taste and judgement in at least choosing a girlfriend.
