I'm afraid to stream videos because I don't know if they throttle you.
I always read the fine print on products, and it clearly says that if you go above 2 GBs, they will slow the connection. I don't know how much Youtube takes up.
Then that's a load of stuff and not really unlimited.You could probably stream a few 4-5 minute videos, don't expect to be able to watch like full length movies on Netflix tho
