I have no idea how to even use Netflix! Do you have to have cable internet to get it on your TV? We watch a lot of sports so I don't think we can do without our cable (or, if we ever change to it, Direct TV) - need to have lived TV for that! Not sure about the expenses. Our cable bill is pretty silly.....
You can use Netflix with your computer or an Xbox, PS3, etc. You just have to sign up for a Netflix account. About $9 a month for streaming.
We aren't big sports watchers either. Only things like the Superbowl and World Series on regular TV.
I guess Skimom is right. We'd have to pay for a lot of streaming services and seasons to add up to the $100 plus a month we were paying!
