buy Ooma instead..
I'm sure I'll get hammered for posting a referral code here, but go to the ooma forums and use one of those to get $40 off an Ooma... $139.999 and free shipping (maybe by dumb luck, you'll use mine) »

Tell TWC to suck an egg.. they could have softened the blow of the $4 fee by boosting the download by 20 megabits and the upload by 10... instead it's good old stick it to the consumer and charge more/get less.
