I think going forward Life Peerages for members of the royal family is a good thing, however, an exception should have been made for Edward.

If he would have accepted a dukedom at the time of his marriage, rather than honor his father and agree to wait until the Edinburgh dukedom was available to be regranted, that dukedom would have been hereditary.

I've already posted elsewhere on the board exactly what I think about how Charles has handled this.
