sbiddle: You could expect to get a 30Mbps symmetrical offering. Unlimited? Yeah right. The economics simply don't stack up. Wireless is a finite resource unless you're talking about wanting an unlimited 5Mbps connection.
In all seriousness you need to get with the reality a little bit - if you want an unlimited 100/50 connection you need to move to a city.
True:/ What do you think would be a realistic data cap and realistic speeds with wireless?
