Guess you missed the recent gaping hole in IP6 on Windows?
IP6 is only really useful in large (i.e. enterprise) environments . It offers no practical benefit to small networks at the moment.
And even enterprise will only switch as they build out new infrastructure. The cost to switch is very high, and the risk is far more concerning than any potential benefit.
