Reading the PVRblog I was reminded of how important the "SAF" is with anything.  When I first discussed TiVo with my wife she understood the concept but didn't see any real value in it outside of a cool tech toy.  At the time we had been using rabbit ears for about 7 years (except for a 6 month stint with cable for $9.99/month) because we just couldn't justify the cost of something we just couldn't use.  With 4 kids we're not sure where we'll be at any given moment.

Time passed and she gave the thumbs up on the purchase.  I hooked everything up the day the TiVo box arrived.  That night was the one show we would try our best at being in front of the TV for (and having the kids in bed) so we could watch it.  We were watching it live with the TiVo and then my wife got a phone call.  I pause the show and my wife is not sure what to think about it...she hangs up and then we continue on.  She was sold at that point.  Then you (all of us) really "get it" when you start understanding the concept of "time shifting" your TV time.  I rarely watch TV before 8:30 or 9pm and I know if there was something I wanted to watch was on..TiVo got it for me no matter what time it was on...I didn't have to specifically tell it like I would a VCR or a lesser product like a digital VCR (read:  non-TiVo DVR's).
