said by JasonOD :FiOS proved that Fiber can be profitable. It just doesn't have the sky high profit margins that wireless has.
DSL can't compete in todays world so why would you expect AT&T to keep throwing money at it?
As VZ proved (and google is about to find out), fibre to the home isn't a viable product for many reasons not just cost. So that leaves wireless, which AT&T is investing a STUNNING amount.
So AT&T will allow people to stay on DSL until wireless matures and comes down in cost (it will). WIN WIN.
