Your monthly plan options: $50/mo just to turn on your connection; then: Plan A: $1 per kWh; Plan B: $100 for 900 kWh, $100 for each additional 900kWh (if you go over by even 1 kWh); Plan C: $200 for 10,000 kWh, $75 for each additional 5,000kWh. But it's an extra $50/mo if you want to use a furnace, air conditioner or refrigerator. And you can never be sure just how much you've used, because their tracking system is always a day behind; so if it's the end of December, and you're worried you're getting close because you've been using the heat AND you just cooked a Christmas ham for 4 hours -- you better just eat cold ham until the new year, or you might get charged an extra $100. (for reference the average US household used 920 kWh in 2008, at average cost of $0.12 per kWh

The biggest difference is, using electricity costs the provider a certain amount per kWh to produce; data streams don't, or at least the cost is insignificant; so it's even more outrageous that the wireless providers are getting away with it. When plans were really unlimited, they might have been able to get away with limiting the devices we could use to pull down that data; but now that we're paying for a set allocation of data, there is no reason they should be able to limit the devices we're allowed to use, charging more for specific devices.
