For everyone following this thread, my letter and Nuance's reply are included in David Pogue's blog from the online version of the NY Times (

Not really a rousing cheer of support for us victims of Nuance's "downgrade" of DNS Preferred 10, but maybe turning the spotlight on their business practices will shame them into lowering the upgrade cost. Yeah, in my dreams!
Or else Jon can claim that Amazing Charts now costs only half as much as DNS....
