Keep in mind that all other features remain the exact same, including a maximum speed of 12MPH, a max incline of 12%, an integrated sound system (no headphones required), and an iPod-compatible music port. Mind you, the 790T does go from 20 integrated calorie-burner programs down to 16, but it comes with an iFit Workout Card that, once plugged in, automatically adjusts the speed and incline, while providing the voice of a personal trainer to guide the user through his or her workout.
