I was previously using a Linksys router and just upgraded to the Netgear 3700N (thanks to people on this board that helped me out) and now I was reading all the reviews on the AirPort Extreme base station. What are you guys using and why? I'm wondering if I should return the Netgear and get the Airport? I'm currently running a few PCs and one iMac. I'm looking for best performance overall, but would focus mostly on file transfers since my external hard drive (which hold ALL my stuff) will be plugged into the router and be used as my main drive on all computers.
