I never really had a feeling about Camilla as a person because she was never in the public eye really.
My partisanship in Camilla's favor over the years was caused by a technicality - I have always felt she was being lied about, I always felt that Diana was savaging the woman, bullying her in a public way. It was chilling to watch. When I realized that Camilla was saying absolutely nothing through-out all of it, I paid attention. I sensed that here was someone of substance. I did not have enough information or exposure to like her but my respect for her grew as I saw her life destroyed as she sustained the nastiness directed at her by the press (egged on by Diana) like a pack of baying hounds. I am one of those who strongly feels that it was Camilla who was wronged by Diana - not vive-versa. - and my hope is that were Diana to have lived and matured in a healthy way she would have undone the damage wrought upon Camilla.
I was startled by the marriage, truth to say, took me by surprise, but in retrospect, it was inspired and tells us that Camilla is not who we were being told she was. More significantly, Charles very likely was finally making a decision that was his - for his own happiness - and for the creation of a solid family life - rather than do yet again what others or a press or a public 'told' him to do or expected him to. He moved on and it was heartening that he had someone to move on with.
Since the wedding my opinion of her has only been verified - this is a woman of considerable inner substance. One has only to look at those around her, she has the respect and affection of all she comes into contact with it seems - not only her husband but also her step children and her in-laws. It seems she has also created a sound and healthy family life for her husband and step-children as well as her own children after divorce - not an easy thing for anyone who has stepped into the step-parent role, but especially in Camilla's case with the drama of the past.
I just found out that William and Kate are using Clarence House for their London base for now - that says something. Camilla is maintaining a welcoming and warm household - she has created a solid family base. Its probably not a household like we 'normal' people have where we live in close proximity - but to even want to be in one's father's and his wife's house says tons.
They do look happy - its a mature relationship. Camilla has really done her duty - been a friend of a kind rarely found. She deserves any honor Charles wishes to bestow on her, I think. She demonstrates what a Queen should be and I think the British should be proud of her. IMO - not that anyone is asking.
