A lot of this makes sense, of course. Well, the little window would have to be around 4 inches in size. To use standard PIP, you need to use your VCR as a second TV tuner. For avid sports fans, it's a godsend, keeping track of two games at once, letting you bounce back and forth to catch the interesting plays, at least in instant replay. But in a situation where, say, one person's show is running long, and the other doesn't want to miss the weather report on the 11 o'clock news, PIP actually might make for a happier marriage, in which case it practically pays for itself.
Some features are a little easier to apply to regular lifestyles.
Anyone who uses an 8mm camcorder knows the annoyance of wiring the camera to the TV set through the back in order to watch the video. If this applies to you, look for a set with the front jacks, like the Panasonic CT20G13. Regular VHS aficionados, on the other hand, may be interested in a TV with a VCR built in. Being prepared, of course, is a good motto all around. Take a look at your viewing habits, your TV's location and the other factors, and you'll be more than ready to scale that wall of video.
