Poynt to me is the best application on my Berry. Movies with reviews and high quality trailers, restaurants, yellow pages and white pages with GPS pinpoint on BB Maps. It's pure win.
Garmin, and the other pay navs for BB are going to lose $$$ if this comes to fruition (assuming is is easy to use and works well). I bet you see price drops coming as a result. I could see Garmin lowering to $49 or keeping it where it is now, but going "lifetime".
Im a big fan of the Poynt app, kinda surprised it was free to be honest. Im wondering if the developer will now try to add a subscription price if they do make voice nav available
