A mesh wi-fi system could form part of a broader Apple home network. Imagine if the HomePod, Apple TV, or future Apple in-home devices, acted as a satellite for a wi-fi access point, as well as being a HomeKit hub; this could get more people to buy these media devices, knowing that they would serve more than one purpose.
In addition, the Time Capsule, an AirPort base station with a built-in hard drive, was a great way to ensure that people backed up their Macs. It meant that both desktop Macs and laptops could be automatically backed up without needed to connect an external hard drive. This was not without its quirks, but the technology was seamless. Apple could have extended this backup to iOS devices as well, allowing local backups instead of or in addition to iCloud backups.
I love my Eero setup, but I’d trade it in a heartbeat for an Apple designed and developed mesh Wi-Fi system that allowed Time Capsules, HomePods, and Apple TVs to extend the network.
