I've been using Foreflight for over a year now for both real world and sim flying. Somewhat recently, the PC app FSXFlight made it possible for FSX users to integrate with Foreflight via WiFi connection for live GPS tracking simulation (X-Plane already had this ability). Today, they stepped it up another notch by allowing the integration of traffic as well to simulate ADS-B. Here are some shots of it in action with PE!
