3. Rover App-Controlled Spy Tank with Night Vision
If the soldiers in Call of Duty were to use an iPhone-controlled device, it'd be this one. The Brookstone Spy Tank allows you to control it using a free app from up to 200 ft away and comes equipped with microphone and video camera capabilities so you could, you know, spy on people and what not. The price was recently slashed down to $100 so now's the time to cop.
