Hulu TV is actually pretty good. The only issue is the lack of an extensive guide organized by time, like something you'd see on a cable TV interface. But even with a relatively slow broadband connection, the video is stable. The service has a decent amount of DVR space and if there is a show that expires, most of them are available through the individual networks.

Have Netflix as well, no explanation needs. And with Roku the Spotify app is great to play music on in the background since there aren't any real audio devices in my home.
