I have used a Parrot Bluetooth Car Kit for a number of years, so I was a little surprised to see their latest product.
Their AR.Drone is a departure from Bluetooth accessories they are known for, but it is indeed an accessory for the iPhone.
The best way to describe this item is a combination of those helicopters you see in shopping mall kiosks and an unmanned predator drone!
The unit can be controlled by an iPhone or iPod touch, just by tilting. Two on-board cameras forward and down/vertical) give you pilot and birds-eye view from your AR.Drone, all transmitted via WiFi.
Sorry, there are no weapons on this bad boy, but you can play virtual games incorporating Augmented Reality (the latest craze in iPhone apps) and you can play indoors or outdoors, alone or versus other AR Drones.
