Say what you will about models and such, but these people are gradually helping to rework the public opinion of transgenders-- in a positive way, I think. Before the relatively recent rise of androgynous and transgender models, the public mental image of TG people was still associated with comedians in drag (i.e. Mrs. Doubtfire). These pop culture pioneers are gradually showing that transgender people can be as beautiful as any other woman. TG is starting to become somewhat "cool". I've always considered the Playboy centerfold thing silly, but this is a cultural acceptance landmark. In the long run I think we'll all benefit from it.
