Well, I didn't use to work for Comcast, But I did used to work for DirecTV and I must say, I've used both services and Cable does have a point as far as the dish direction and weather issues. Moisture in general will black your satellite signal, try to imagine a satellite signal as a beam of light and a rain drop or any form of water will act like a prism, refracting the light as it goes through the water. This interrupts your signal but it will come back as soon as the weather passes. Also another issue is dish direction, this all depends on your location in the States as well. The main DirecTV Satellite, for us in Utah is to the South East, whilest the main Echostar (Dish Network) satellite is a few degrees off of direct South and if your Dish is not directed in that position you will loose signal and will have to either reposition it yourself or have a professional do it. In most cases the dish is secured so well that this wouldn't happen, it really all depends on how good of an installation you had and if you have kids who live in your neighborhood that play ball a lot. These are all factors that you need to consider when going with a Dish.
On the other hand, cable is a chaotic beast, if you loose signal with cable, and you will, trust me, you will have no idea what is going on because the cable lines are under the ground where they could be cut into with a shovel or something of this manner, OR in the worst case scenario, it's something on the cable company's side or has something to do with your local city utilities cutting into the ground and cutting some wires which could be fixed in an hour, or a week; it really just depends upon how many people there are with cable in your area.
So ultimately, it's your call. You WILL get a better picture and more choices in viewing options with Dish Viewing, or you can have the "always on" (pun intended) cable signal that looks extremely pixelated with little blocks of color that are annoying as hell.

I hope this helps with your decision making.
