Apple either now rule the world or they have killed multi-touch enabled devices manufactured by anyone except Apple. The patent granted recently to Apple is exactly why I hate patents in general and especially software patents. They don't protect IP. Apple didn't invent touch and it didn't invent multi-touch. It didn't even invent gestures (I hate gestures too btw). The really sad news is Apple has already shown signs that it is becoming a patent troll.
What software patents do is allow companies to take other peoples IP that was invented aeons ago and levy a tax on it. DailyTech has more details.
