Don't get me wrong, DVR is probably one of my favorite inventions of all time. My problem with it is I become dependent upon it when I'm not actually watching tv. Somehow my mind doesn't make the connection that you just can't rewind real life if you let your mind wander. I've actually had moments where I missed something, and thought it was no big deal because I could just press the rewind button, go back and get the information, then catch up when nothing really important was going on. Imagine my frustration when I realize that not only is that information gone forever, but I also just missed another 30 seconds of whatever was going on because I had to convince myself that I couldn't just rewind in this situation. It happens all the time when I'm listening to the radio. I think it's more frustrating because it's just like tv, just without pictures. The technology to do it is totally there, I guess it's not worth it to most people. Or they don't want people wrecking their cars while trying to rewind their radios. If someone could only invent real life DVR. Unfortunately this would likely require some type of time travel mechanism, and I'm not sure how close the scientists are to that yet.
Despite my issue, there is around a 0 percent chance I will cancel my DVR service because well, it's pretty awesome to be able to watch one thing and record another, record two things at once, or rewind to see a score on the bottom of the screen you missed all without having to use a single VHS tape (saving the planet one tv show at a time).
