The ninth thing is to lower barriers to adoption. Here are the cases where you’ve created the world's greatest mousetrap, the nuclear power mousetrap. You kill mice better than anybody in the history of mankind. Mouse goes in there, there's a little explosion, a little mushroom cloud and the mouse is gone. You murder mice really well. You got the design from Lawrence Livermore or you stole it from Los Alamos, I don't how you got it. Somehow, you really murder mice well. So here are the barriers to adoption. First of all, your mousetrap is nuclear-powered. However, you need a PhD in Applied Physics to set the mousetrap. The learning curve is so high. It's almost as difficult as setting the clock on a VCR. It's that high, all right? The fundamental model of a metaphor that you should aspire to is you open the box, you plug in the cords, you go. That's what it should be like. You should not need a PhD in Physics to set your mousetrap. Flatten the learning curve. By contrast, if any of you buy a BMW, there's something in the BMW called an iDrive which is their interface for their electronics. If you take a two-hour course you will then be able to change the radio station. That is the antithesis of flattening the learning curve. Second point is, you never ask people to do something that you yourself would not do. You wouldn't go back to school to get a PhD in Physics to set a mousetrap. You wouldn't drive 300 miles to drop off a dead radioactive mouse. You wouldn't pay $250 thousand dollars for a mousetrap. Don't expect customers to do this either. The reason why there's a washing machine in this picture is because I have a positive example which is the Kauai Hyatt Regency. The Kauai Hyatt Regency, in every wing of the hotel there's a laundry room. That means there's one less guestroom. It means that people send out less laundry through the laundry system. Then if you went into the laundry room, you would see that the washers and driers are free. So at the H...
