There is no way i would go through the trouble of putting an outlet on the wall without pulling at least 1 RG6 and 2 Cat5E or Cat6.

I haven't played a disc in ten years. Every time i test one at a clients house i want to smash it because of the ten minute wait to watch a movie. I may be exaggerating but the ads and the FBI nonsense...no thanks.

As far as mounting the TV goes...it always depends on the TV and where its going. Sometimes a nice piece of furniture that can hold equipment and a center channel fits a space just fine. Other times the wall mount with gear hidden is best. I dont think there is a set trend for this. Whatever you do with them these days they take up very little space.
