I occasionally get kicked down to 128 kbps for a few hours at the end of a month and a surprisingly large fraction of the internet still works.

They are targeting voice which can go really low, but a moderately optimistic ~100kps is vastly better than 0. Much below that and the number of people using it is going to drop near 0.

Yeah, it says so in my AT&T contract as well. And I was concerned when I first signed up. But I haven't ever actually seen it happen.

AT&T actually enforces it for tethering. If I really need something I can still use my phone, but it’s convenient to leave the phone where it gets reception and then use the tablet nearby.
