I was perusing the insanely slow Xfinity site looking at my account settings and at the bottom of the page it displays "Data usage meter". I am lucky enough to live in an area where Comcast (Xfinity) is trialing giving people a set amount of data per month and the charging $10 for every 50GB over their allotted amount. Only like 10 cities doing this.... I'm so lucky. Thankfully all my kids are little right now so not a ton of people using up the data. I had read somewhere that is how it is done in Canada, but was grateful we didn't have that here. Oh well.
