YES!!! That is EXACTLY what we are saying. The "data" is free. The "mechanicals" of the data calculation are what you pay for. Look, you've provided no explanation within the framework of physics to explain where this "lost" energy goes. As I pointed out earlier, a dimensional analysis of energy->data DOES NOT bear out the assertion that some portion of the energy put into a PC comes out as anything but photons of one wavelength or another. Look, I'm not trying to be a troll or anything here, and normally I'd let this kind of misapprehension go, but this kind of flawed idea of physics is the kind of thing that lets people believe that perpetual motion machines are possible or that cars that "run on water" are being suppressed by Detroit or that solar panels can provide enough hydrogen for them to drive their Escalade for free.
