Not quite true. Pacbell broadband big competitor is ATT/Athome Cable. And if Pacbell doesnt beef up it DSL service and performance to my ISP soon, I'll dump this home DSL and get on cable.
700kbps on DSL or 3Mbits on cable - which would you pick?
This assumes you have a choice. Unfortunately, most businesses don't. The cable companies cater to home users. SBC has wiped out the business competition, so there is no choice for them.
