About time Apple made this news official.
Even back in 2013, the AirPort Extreme didn't stand out from others in terms of routing performance.
Either be the best in the market or go home. Apple made the right decision.
I respectfully disagree. Normal consumer WiFi routers had very poor performance in my house due to the massive amount of rebar concrete in the walls and floors. (Standard building practice here). My single AirPort Extreme (old model, kinda looks like a Mac mini) could supply my entire house. When the news broke that Apple was discontinuing (not unexpected) I replaced that aging setup with two ubiquiti AC-PRO AP’s to do the same. (Spread over two floors, they hand off clients to each other).
My personal and professional experience is that the airport (extreme) outclassed all the consumer level stuff and even some of the professional stuff.
