I switched away from Comcast over to Verizon because Comcast has a 250 GB cap (even if you're paying for their 50/10 service), and Verizon doesn't cap you. At 50 Mbit down from Comcast I could use up my entire monthly allowance in just over 11 hours (without any upstream, math may be suspect it's early). That seems crazy to me. Vote with your dollars (if you're lucky enough to have options) and let them know that caps aren't a good thing.
