Some people say Star Wars is the greatest Sci-Fi film ever, some say Blade Runner, others say Alien. NO ONE SAYS BATTLEFIELD EARTH! How do we know? Because the whole movie is just sitting there for free on YouTube. Anyways, the other movie that people revere as perhaps one of the greatest ever in the genre is 2001: A Space Odyssey. If you’re an iPhone user and a fan of the flick, you need this IRIS 9000 Voice Control Module ($60). Besides being a dead ringer for HAL 9000, it also gives you some room between you and your phone while still letting you boss Siri around.
