Netflix came out with a tv box that will stream movies to your tv!
They already have the capability of streaming movies to your pc and now a unit can be purchased so you can watch it on your tv. This box will be attached to your tv and will have features like a dvr where you can fast forward and rewind.
If you have any of the unlimited plans that they have you will still receive you dvds just like before. So the $99 one time fee will be the only cost.
