Was just thinking about the branding aspects and capabilities of SharePoint in internet facing sites; came across these very good examples;
1) Ferrari - http://www.ferrari.com/
2) Goodman - http://www.goodman.com/
3) Cadburies - http://www.cadbury.com/
4) Conservation International - http://www.conservation.org/
5) Swiss Airways - http://www.swiss.com
6) Hyro - http://www.hyro.com
7) Rado - http://www.rado.com
8) 1 by Youth - http://www.1byyouth.com
9) WesternAustralia - http://www.westernaustralia.com/
10) Hyder Consulting - http://www.hyderconsulting.com
I picked some of these up from the sites given below as reference, you could go check them out for more information;
1) pinkpetrol gives you some nice commentary on the sites as well.
2) wssdemo is an excellent example of the use of silverlight in a site.
3) sharepointjoel gives you some of the sites of the more prominent companies.
