Why we won't see TV-computer convergence:

McCracken says most homes are consolidating around a two-hub model. A PC (or Mac) with some multimedia features anchors the home office, while a TV with some computerized gear -- think TiVo, not desktop computer -- owns the living room. Tech marketers talk about the "2-foot interface" of the PC versus the "10-foot interface" of the TV. When you use a computer, you want to lean forward and engage with the thing, typing and clicking and multitasking. When you watch Lost, you want to sit back and put your feet up on the couch. My tech-savvy friends who can afford anything they want set up a huge HDTV with TiVo, cable, and DVD players -- then sit in front of it with a laptop on their knees. They use Google and AIM while watching TV, but they keep their 2-foot and 10-foot gadgets separate.

Sounds a lot like our house! (Via Marginal Revolution.)
