I got TiVo for my birthday, and I have to tell you, this is the most amazing invention that people don't even realize they need, until it starts doing its thing. If you can get it, it is so worth it! Right now we have it set to pick up all episodes of about 12 different shows--I no longer have to remember what night things are on--and if I'm watching something live, and then need to put the kids to bed, I just push "pause" and it stops!
Pardon me while I date myself, but I remember the ancient days of cooking a frozen enchilada in the oven for 45 minutes--and then my Dad went out and bought a microwave with a big minute dial on it. Suddenly you could have a TV dinner in 5 minutes , and things have never been the same since. THAT is like TiVo now.
