Hi guys I need a new router to make my internet at home wireless. I'm getting a 50mbit line and would like to get a router from Apple. What exactly are the differences between the two routers? I don't need other features than the router-thing, so don't care about Lan-ports, usb-ports, Airplay and so on. Should I just buy an Express or go with the Extreme, when I only need a router for making my connection wireless? I'll have about 10 devices on the network.
