Let me bring you up to speed a lil bit
The ESPN app lets you watch a ton of shyt, even if you didn't have cable you can watch stuff like any NBA game on ESPN once its finished (or via the app if you have ESPN at home)
The NFL app will keep track of your fantasy shyt in real time while you watch your game, it also has its own channel within the app called NFL Live NOW (similar to NFL Network)
The Web browser which is called Microsoft Edge can handle most websites including the ones that let you eat for free
I watched McGreggor/Diaz 2 in HD no problems, movie stream sites work, you can share anything you have via onedrive with anyone of your friends and.. AND.. whatever you have "shared" for your friends? Shows up in there built in xbox TV guide called "One Guide"
Now thats some next level shyt that most people on this site don't even do, but you can do it
Skype works great, amazing if you have Kinect. Try to get used to asking Cortana to take you places like "network settings" and you won't have to go to settings, then finding the network tab... it just cuts out alot of extra steps if you get good with it.
So if you are using a headset of any kind, cortana is your bytch
You can even ask shyt like "Hey Cortana, whats the weather" and watch what happens slim. Greener side, fukkin other nikkaz bytches
