Absolutely. We're not going to miss it. I'm thinking about an HD antenna, but we're a little far from the bigger stations, so I don't know how good the service would be. But we love being able to watch pretty much anything we want, whenever we want to. I have like 5 tv series in my netflix queue right now. Not like we'll run out of entertainment anytime soon.
This is what I have in my attic. It's about 25' up and I get all the OTA channels for the New Orleans area in Mandeville. http://www.monoprice.com/Product?c_id=109&cp_id=10901&cs_id=1090102&p_id=4730&seq=1&format=2
I cut the cord about four years ago. Besides the OTA channels, I have a subscription to Netflix. I also have access to a Hulu account. As far as hardware, I have two Roku boxes and an Amazon Fire TV stick that I haven't tried out yet. Once football season rolls around again, I am going to give Sling TV a try. For $20/month with no contract, it's cheaper than taking the family out to eat somewhere to watch LSU games.
I keep telling myself that I am going to get a Slingbox and hook it up to my daughter's cable at her college but I haven't gotten around to it yet. I've heard of forums where you can find people sharing their Slingbox with others but I haven't bothered looking for it since I don't have a Slingbox right now.
