Windows Phone Thoughts: DialerAce Predictive Dialer

"We have just released predictive smartphone dialer, DialerAce, whose intelligent algorithm enables an input-free prediction that generates a smart call list. Unlike the usual passive mobile dialers, the call list will be filled with people that you want to or should be contacting. DialerAce, through its algorithm, actively recommends your next call based on your tendencies, habits, upcoming events and other information, such as birthday and anniversary."

It is in beta right now, so fair warning. There is a list of features a the software developer's website. See if this is something you'd be interested in and then sign up for the beta.
