I've enjoyed hulu since the beta days and watch on an infrequent basis. As has been mentioned in this thread multiple times, it IS a resource hog. My experience is:

1. On my macbook pro with dsl connection - works very well. Enjoyable.

2. On my apple tv using couch surfer (again with dsl connection). Sound is great, video is "jumpy" but watchable for short periods. Overall, not so enjoyable.

3. On my N800 with home dsl. Sound is OK, video is almost useless.

4. On my N800 using a fat pipe Internet connection I sometimes have access to, sound is great, video is very 'jumpy' but almost watchable.

Given that the performance is marginal even on a one GHz apple tv, I doubt that hulu will ever be very useful on the NIT unless they decide to offer a lower resolution option for their videos.
