What's the advantage to the BowFlex home gym over free weights?

With a BowFlex® home gym, you don't have to lift a 45 lb plate to get 45lbs (20.4 kg) of resistance. The resistance has very little inertia, which promotes a safer workout than free weights. You would need a room full of free weight equipment to match the number of exercises that can be done on the BowFlex® home gym.
