Yes but the imperfect incentives isn't punishing "consumption" of electronic devices. One clear example is the consumer version of a surround system with built in bluray. The day that the blu-ray drive gives up the consumer goes out buys a new one and throws out the old one. Now if we compare that to the enthusiast and buys a heavy receiver, separate speakers, and blu-ray player and is taxed individually on each component. What happens the day blu-ray gives up... he goes out and buys new blu-ray and keeps the old stuff. Same goes for the pc-gamer that builds his own PC. Buys individual components gets taxed on each, upgrades and replacements of components are taxed. But a regular consumer goes out and buys a flimsy laptop taxed less and throws away the laptop when it breaks.
