Yeah dude, we get it. Its the sole fact that they patent the idea and not blueprints/schematics of such a devices the part that bothers us. If it was that way, heck, I can think of something 'futuristic' patent it, and voilà. Apple probably has little info on the technical issues involved, when they are only 'in the works' of that development. And yet they file the idea, with NO major background on HOW to do it.
