If you need a GB ethernet switch, they are easily come by, and in port numbers to suit your needs.
I think Apple are aiming at having all multimedia and data transfers done through wireless N not ethernet. The ethernet ports are there I think to allow you to easily get everything access to your broadband, to attach ethernet storage, and other enabled devices - and other pre-N Macs - to your N network. I also wonder what other ethernet devices they might have lined up. I personally would have liked to see 2 USB ports. I dont think they intend this WAP to be more than that.
