Not to mention the fact that the whole idea of VOIP is to simplify IT and focus on converging data and voice networks.

It's ludicrous to think that two ports will be better than one if we're setting up our VLANs and QOS properly. A phone takes very, very little bandwidth away from the desktop and a decent one will support tagging its frames for the alternate voice VLAN.
