Off the top of my head:
Between the 3 people that live here (girlfriend, apartment mate, and I), and the roommates girlfriend who is frequently over, there are up to: 3 Androids, 1 Blackberry, 4 laptops, a chromebook, a media center, and home file/media server. This doesn't include assorted other devices belonging to friends who visit regularly. There is actually enough traffic that I am considering putting in a second access point to lesson the peak loads.
