Thanks for the tip! ROKU rocks!
I've been using Roku exclusively for several years. Cut the cords 100% to cable TV and broadcast. To tip toe into Roku, download the free app to try it out. Watch on your mobile or AirPlay onto your TV if the TV supports it. If it.clicks for you, purchase a Roku box to get a way better experience with lots more channels.
On the edge though with adding ESPN as a paid subscription. Really want college sports and that will get me most in my range of interests. Yes, I am a cheapskate! I love free!
