@pcolvin yes it is expensive, and yes I have 5 in my house an additional 2 "all weather" outside and one in my workshop (woodworker etc hobbies).
...But the Eero's aren't the point, I previously used 3 multi-antenna routers in my previous home. Couple of hundred dollars, so... Why the Eero's? Easier to maintain a reliable and SAFE network. Cat-something is much cheaper, but labor intensive to wire a home. Today, starting from scratch: I would absolutely run fiber with a couple of WAPs where it makes sense.
The best way really to set up a home network is to use the big bandwidth where performance is key (less and less important with the advances in wireless) but to also SEGREGATE your network into purpose-specific sub-nets (in both senses): Such as, a dedicated "link" (wireless subnet on a dedicated channel, or fiber, or Cat-something) from the ISP router to these different sub-nets. For instance, a home office with multiple inter-communicating devices should not be contending with traffic for the TV or streaming.
