It's not capped at 100 minutes though, it just includes that many. They could keep talking more than 7 hours past that before the overage costs as much as the family plan with half the data.
Yep, if you talk another 100 minutes, you pay $40 that month instead of $30. I combine it with having gvoice ring my landline when I'm at home, and the landline is $3/mo unlimited voip via an Ooma box.
