I'm saying that many things you own would work better if they had a little computing power in them, or if they had access to a computer. So, for instance, it would be too expensive to put a PID controller in your toaster oven. That's why there's a simple thermostat and a simple timer in there. But imagine if your toaster could send temperature data in a bluetooth-esque way to your tablet. The tablet does the proportional-integral-derivative calculations and sends commands back to the toaster. So you get all of the benefits of PID controlled temperature without the cost of the PID controller. Another idea (likely in the works somewhere): tablet as guitar effects pedal.
