Add in the fact that it's about 1/3 commercials (with some exceptions, like PBS) and I just can't do it. I literally have not seen a TV commercial since I was at my parents house last Christmas. It also ties me to watching TV on their schedule, not mine. I get out of work at 11 am and for me personally nothing worth watching ever comes on in the middle of the day on those channels available over the air.
I'm not arguing for cable subscription either. Better reception sure, but same problem with commercials and scheduling. DVR fixes that somewhat, sure, but I want to see a program uninterrupted, not fast forwarding through commercials. And WAY overpriced.
Streaming isn't perfect, and it's but it meets what I need done way more then that antenna does.
