That's just too sad. I was thinking recently how my 3 year old AirPort express was the best router I've owned. These routers were always super easy to configure and I remember maybe one reboot in its lifetime... it powers:
2 MBP pros;
2 iPhones
1 Apple TV
1 Roomba 980 cleaning bot
1 Footbot - Air quality monitoring
1 Apple Watch
1 Sony PS4
... everything working flawlessly
Sad day for me.
