It has has been well known for a while that it was coming, but Apple finally killed off their router line. Which is a shame, I had an AirPort Extreme and it was one of the easiest routers I have used, setup was painless and management was just as easy.
I switched to the Eero mesh system a while back and have not looked back since, but it is still saddens me to say goodbye to the AirPort devices. My mesh system has fixed all of my WiFi dropping and speed issues around the house. My AppleTV has never been happier!
