Why don't they focus on the reliability of their service first?
Why not focus on customer support, as a whole, first? They have a well deserved reputation for being one of the worst companies to work with.
Comcast is not any where near 100% reliable, I'd say more like 90%.
They have (or had, for a long time) crap modems that were only part of the problem.
People, businesses and government offices are putting all their eggs in this basket with internet, phone and TV, all coming in on one fat pipe.
When it goes down, they are massively screwed.
And it happens all too often, far more often than DSL. DSL might be slow and crappy but it is more reliable than cable.
Don't get me wrong - Comcast know what they are doing when it comes to slinging massive amounts of data great distances at high speed. They really do, and their internet is amazingly fast.
But why try to go faster when there are too many times it's going nowhere?
This, not to mention their hidden data cap. If they offer this massive bandwidth do they leave the data cap where it is? HMMM???
