Atrix Plus Laptop Companion Dock = Charged for something you aren't using TETHERING
Why would you charge for tethering with the atrix laptop companion dock when what you are doing technically isn't tethering? Forcing users to have a tethering plan with the atrix laptop dock would be akin to forcing someone who used a bluetooth keyboard with their smartphone.
Or for how is the way the dock is implemented different than sending video out to tv. Some smartphones have this capability and allow you to play media from phone to tv, look at pictures, or even view apps or your browser on a large LCD screen which is no different than how the dock companion is implemented.
So i reiterate why should pay a tethering plan to use the dock when you aren't tethering?
For those who aren't aware of what the laptop companion dock is....its simply a screen and keyboard/mouse and thus allows viewing of your phone on a bigger screen with full keyboard. The dock does not have its own processor, memory, or OS. You are using the phone as the brain. This isn't using the data connection of your phone as a modem for a full fledged laptop that has its own cpu, memory, and OS.
