I am sure they use complicated models. I prefer to use a simpler one: theft.Thursday night saw a grand heist from a San Carlos, Calif., Best Buy that suggests the iPad 2 will be in extreme demand over the next couple weeks.In this particular incident, as chronicled by CBS San Francisco, thieves broke into Best Buy and took a whole steel rack of iPads containing at least 125 of the precious machines.You might wonder how they did this. @Yungjohnnybravo @TatWZA
