I have a quick question .... I just did a bandwidth speed test w my cable modem and it registers 2.5 Mbits/sec .... what you kinda expect (Comcast advertises 3 Mbits/sec). Now why would anyone rent a T1 for $500/month if it gives lower speed of 1.5 Mbits/sec? .... Just figuring out if we need a T1 line for a dorm with 10 people all doing IChat, apperently a cable modem and a $39/month subscriptio would do.
