I have no problem with this product, but I see a problem with what it will lead to. If your like most people you get your Internet from your cable company. As soon as the cable companies see a drop in cable subscriptions alongside increased data usage you know we will start paying by the gb for our Internet.
There is clear precedent, the wireless companies, of which we are all familiar with, used to charge for minutes and give you all the data you wanted. Fast forward 10 years and you'll see that the equation has flip flopped. Because people could make calls using data. Your cable company isn't going to sit back and let you watch something for free, they're going to find a way to charge you for it.
OK rant over.
