This is copied from an e-mail I sent this morning. It's in response to a dad describing how his 5 year-old who couldn't grok the fact that his grandma's house didn't have TiVo. I agree with the kid - watching TV without TiVo is like living among Troglodytes. Am I the only one that finds himself subconsciously trying to hit an instant replay movie when I see a cool scene in the movies? (only to be disappointed that movie theaters don't have TiVo)

Other things that need TiVo-like functionality:
- radios
- people (what was that again?)
- snowboards

Follow-up: others have since suggested cars, guns, and sex.
