I have 20/1 via TW. They tried rolling out a cap here in our market but it was fought heavily by both consumers and eventually politicians. It was going to be like a 60 - 80GB cap with $1/GB overage. They withdrew pending "consumer education." Because I use 80GB/mo they classify me as a "heavy user". I stream Netflix, Hulu, and d/l a linux distro or 2 from time to time. Heck, if I install Windows, that's 3GB of updates before your even started. I pay for the service. And honestly, I rarely ever peg the line. I can have 6 simultaneous downloads from 6 different servers and still have room to spare. Most FTP sites won't serve more than 2Mbps and most shared hosting sites are ~200kbps. DoS protection most likely. I'm happy with my 20. I just wish it was 2-5 up instead of only 1. (TW's standard tier in this market is 10M/768k).
