If you want to go bleeding edge, consider the S33 with its 2.5Gbit ethernet port. No guarantees however that Cox will ever activate or use the port. It's also not very useful unless Cox starts offering plans >1Gbps. One catch is that Gigablast in some areas may be passing something like 1.01 or 1.06Gbps, so you may get a tiny bit more IF there is over provisioning on Gigablast and IF the 2.5Gbps port is active and IF your router, switch, and Mac are all equipped with 2.5Gbit or faster NICs and IF the server you're then connected to has the ability to push that kind of bandwidth.
