The guy who titled his review "poor poor poor" has no idea what he is talking about. A5.com is FAR from the only provider in town. He had his choice of cable (Insight/Comcast), DSL (available from a number of companies), satellite (granted, might not have been able to mount a dish on his building, but unlikely), etc. The only exception to this is if he was living in a college student apartment (a near-campus building where everything, including Internet access, is included). Now think about this -- imagine that you have a building full of college students all downloading music, videos, and other high-bandwidth items. You can imagine how fast the bandwidth is going to be used up. This is no fault of A5.com. It's the nature of the beast when you are sharing Internet connectivity in a building full of students.
I've used A5 for years and I love it. They even have wireless service available in parts of Bloomington. It's run by a great group of guys.
