I manage an IT company and after years of using various WiFi routers, nothing has come close to the awesome performance of Apple's Extreme. Previous systems all have had issues with interference from various devices, cordless phones, microwave's etc (not just 2.4GHz devices either) not so with Apple. The device manager let's you know when new firmware is available and the unit publishes two separate WiFi networks (business and guest) with different security options and IP ranges for each. We are a Windows shop at work and have had no compatibility issues.
Lucked in to an Airport Extreme at a thrift store for USD0.47 (47 cents). Needed a power supply, but that $15.00 aside, it cost me next to nothing and is a better perfromer than a similar "mainstream" router - more reliable and faster as well. And it's the only router which will **reliably** allow my Toshiba Libretto 110 to connect to the Internet (cabled, of course)...
Since when is three routers considered an "array of Wi-Fi routers" (and let's be honest, it's really only two)? I had to read the article to find out what product line the author was referring to that I didn't know about!
Guess the author forgot that the express isn't even a router. It doesn't route traffic, it only will act as a repeater.
Did you do any homework before posting your comment? The Airport Express provides a NAT firewall, MAC address filtering, 802.1X, PEAP, LEAP, TTLS, TLS and FAST security, NAT, DHCP, PPPoE, VPN, DNS Proxy and SNMP services. You connect a DSL or cable modem to its Ethernet port. Read the specs: http://www.apple.com/airportexpress/specs.html.
