If you can get those channels on the Internet, then will you leave Direct TV?
Maybe... I also like the convenience of being able to simply turn on the TV and browsing through the program listings... and so does my wife.
While I'm pretty tech savvy, I still don't like watching TV on the computer (especially since I have a few nice big TV's), and going through the gyrations to send stuff from a tablet or my PC to a big TV is a bit of a pain (and virtually impossible for my wife to manage).
I do have a smart TV in one room, and a DVD player in the other room with smart TV capabilities, and I've fiddled with Hulu and NetFlix on those (my daughter's accounts), as well as Crackle... but they're tedious when trying to search for something.
