So Apple is getting out of the wifi router game. My current AirPort Express is the one released in 2008, I’ve had it since 2012. So do I replace it or buy a just-in-case spare? If so, do I get another Express (the 2nd gen) with two Ethernet ports for$149 or spend $30 more on a used 5th gen Extreme? I can’t afford/justify the newer 802.11ac tallboy design.
