Let me chime in. We dropped Dish network for Comcast as well when we moved into our new house last month. Here is my experience so far:

*Install Was Bumped 4 days in a row
*Internet Speed is only at 3 megs not the 6+ they claim
*Cable box in living room keeps turning itself off and resetting every 20 minutes, so I call the useless ghetto folk they call phone rep's, they have a guy come out and give me another box, and it still is doing it.
*GHETTO ASS CUSTOMER SERVICE REPS in case I didnt make that clear in the one above this.
*On Demand is down pretty much every week

Should I go on?
