The Roku box is cool, but if you already have Tivo and a Netflix account you don't need it, as Tivo has an interface to the same thing. Tivo has absolutely changed the way I watch TV, and the addition of the Netflix "Watch It Now" feature is terrific.

I appreciate what Hulu brings, but I haven't found it to be a very user-friendly experience--difficult to fast-forward, rewind, etc. without having to sit through their ads.
