I am a current Xfinity x1 subscriber who loves there service but not their price. Ondemand is excellent dir and guide interface is easy to use. how does hopper 3 compare to x1 in regards to lag and on demand? how responsive are the wireless joeys should i avoid them and get regular joeys? i haven't been with dish in over 5 years. when i left dish and went to comcast i noticed picture quality was better on comcast has picture quality improved?
