Turn your brain off and on, watching TV on the web.

Is watching TV on your television vs. on your computer the same... or different?

I believe it was Steve Jobs who said when people turn on the TV they turn their mind off, when they go on the computer, they turn their mind on. I wonder... is their scientific studies to prove this statement, and with the rise of websites like Hulu.com that feature on-demand television content, does watching television on the computer have the same brainwave effect as watching on that big flat screen? What do you think?
