I like Netflix streaming, but I doubt that it represents 10% of what I watch. I think a lot of it has to do with the cable guide vs. the clumsy Netflix search.
The Amazon Prime user interface was HUGELY improved in the past month or so. What a difference. Finally is usable, well organized and has good search.
A show I watched on my computer on NetFlix is nowhere to be found on the TV. Weird.
