I set up a Google WiFi at home (one as a gateway/firewall with two satellites connected by GigE). I'm paying for 250Mbits/sec from Comcast and regularly see more than that, even over WiFi. I also like their auto-updating and security stories.

The place where I'm less than happy is when Comcast goes down, the amount of diagnosis provided by Google could be better. Like, since the client runs on the phone, it could just as well have a button to disconnect from the WiFi and probe for your home at its last-known IP address from some Google server somewhere.
