I don't think we can make this generalization. It is not uncommon to
have single AP in the coffee shops (WISP case), or multiple APs in small
offices (I had three in my 40 people office) today. And multiple APs in
homes in near future.

I think you are assuming the hosts are stationary in the office/home.
But note that people walk in and out of these locations with laptops,
PDAs, IP-enabled phones, etc.
