It's like the constant copy protection battle here... we figure out how to get around their attempts to stop us, they find ANOTHER way to stop us... WE find ANOTHER!!!! loophole... it's frakking ridiculous, I'd just go back to unlimited data and charge like 10 for unlimited tethering.... that would certainly stop all of the "illegal" tethering. I'd even be willing to pay for it.
You can do almost as much on these phones, if not as much, as you can on most PCs now... so the point of using more traffic on a laptop is pretty moot. kinda funny to watch though.
Edit: I don't go to the field anymore, so the only thing I tether is my wifi xoom over BT and... with the bionic now I don't even have to do that.
