I don't think people don't buy Airport because it doesn't have web interface. I guess the real reason is the price. If you looks at all routers at $200 price range, Airport probably has the worst looking spec.
Whenever I visit my parents I usually bring replacement hardware for whatever is broken. When I first got them their Airport Extreme, I replaced it after 5 years. I got them an Asus router with a really impressive wifi range, but it broke after just 1 year. Now they're back with the latest Airport Extreme.
It's a bit pricey for the specs but it's very reliable. I use 2 at home, that are bridged via gigabit ethernet, and they're pretty good. My only complain is that they don't have VLAN support (IPTV) and their wifi range is really bad.
I'm hoping the OnHub will be good but I need a way to configure it without Internet
