I was going to pick up a new Airport Extreme today, as I've been having a few issues with my 3-4 year old Netgear router. I was somewhat floored to discover (via Google searching) that Apple have never supported QoS (Quality of service) on their routers. Is there some rationale for this? I have IP phone services (both a work phone that connects via a SIP gateway as well as Ooma VoIP home phone service) and to get reliable performance QoS is needed. I'm really just looking for insight, since it appears I will have to go with a non Apple product to fill this gap.
