For the "other side" to this you can read these articles:

PDF warning! It is a bit long, at 28 pages, but does make the "anti-neutrality" case in a clear manner.

Also looks at the potential problems of net neutrality legislation.

For the "other side" to this you can read these articles:

Google and others may be argued, but Skype is a real sticking point. Sprint offers VOIP, and requiring Skype to pay extra to offer their VOIP is anticompetitive.

For the rest, this is simply greed. Telcos already get paid by Google et. al. to push traffic out, and telcos already get paid by the consumers to take traffic in. If they're hurting for money to cover infrastructure, then those rates simply need to go up.

I found Swanson's essay on the Mises Institute site reasonable, noting both potential problems with net neutrality rules and the existing problem with the government-created broadband monopolies held by the incumbent telcos. Thierer's essay on the Cato site made a painfully strained, if not downright risible, attempt to handwave away the latter issue.
