Well the HIC is just for people who have the router in a different location and do not have very good WiFi. Wireless doesn't always cut it. I prefer to have mine connected by wire.
Agree, probably much less potential for problems and support calls with the HIC than with wireless.
It's not really a line item they are looking to make a profit on anyway. Sure they want to cover their costs, but more importantly they want folks connected for the data capture and revenue producing potential.
