The trouble is, the AirPort Extreme Base Station is pretty poor value for anyone in the UK. At £119, cheaper solutions are already available from many other vendors.
It also doesn't include an ADSL modem - largely due to the limited countries ADSL modem routers can be marketed, but will still be good for UK punters connecting through cable broadband.
As well as a WAN Ethernet port, the router has three LAN ports for wired connections to other computers instead of the usual four.
The one interesting feature is a built-in USB port, enabling to print wirelessly to a USB printer or share any external USB hard drive.
