Good deal for who? They would love for everyone to jump on that tier, its free money, and especially when 99% of households NEVER, surpass more than like 30Mbps at one time.
I would like to know where you got 99% of households only using up to 30Mbps at any one time. I see the rise of cloud services making super fast broadband a necessity. Look at why Google is trying to deliver 1Gbps to households. Online services have been on the increase year over year.
