Tablet that can stream TV?

[frannn]

I have a Nook Color that is modified via an sd card, in order to stream Netflix. I was lucky enough to get a Touchpad when the price dropped, but will not open it till Xmas. Can either one of these play (free) Hulu and stream stuff from online? I don't mean Youtube, more so the shows from the online regular network websites...like if I missed an episode of one of my tv shows thats available on the computer. Do I need a different device for this?
Also wanted to ask if there is a product that picks up just the tv audio (so I can listen but not watch at work).
