I have been reading up on the airport express and as I am about to have to buy a new router when my roommate leaves. 1) Is the main feature of this, just the fact it is easy to setup and control over all apple devices? Versus other router brands on the market? 2) I am going to need to setup a network printer which I see you just plug in the USB cable to the express. Now if I wanted to have a network drive as well, is it easy to add a network storage device on the Express? I know for the Extreme it already comes with options to add both, can I add more than one external storage device? 3) How is the built in firewall for them? Can you turn it on/off and use your own if needed? 4) I also see that you cannot hardwire a desktop to the express without getting much slower speeds than if you would just connect on wifi, correct? 5) Why did apply drop Airplay on the Extreme? 6) I guess the big thing I am just trying to figure out is ... why these 2 routers command so much more money than other routers on the market. Is it because of that damn black apple logo again?
