Well, MacOS has had IPv6 enabled by default for years now. That  
doesn't mean you actually get to use IPv6, because for that you also  
need an IPv6 router on your subnet, which most people don't have.

In Windows, when you enable IPv6 this also enables 6to4 and Teredo,  
so you can enjoy IPv6 connectivity without a local IPv6 router, but I  
don't think enabling 6to4 by default and preferring it over IPv4 is a  
good move, the 6to4 relays would melt within hours. (By the way, the  
past weeks I discovered that in XP due to prefix policy issues IPv4  
connectivity is preferred over 6to4 connectivity towards non-6to4

Is that so terrible?
