Good for some, needless for others. I've heard of a lot of problems with the TPMS giving false readings or going haywire. Either way, I check my tire pressure every time I go out to my car and bought a small air compressor that plugs directly into the lighter. I also have a rim that is bent that sometimes likes to leak 15 pounds of pressure out overnight (not all the time, just when it feels like it), and I'm sure the TPMS would love to alert me of this matter. Since I check my own air meticulously, I don't need it. Just another system that something could go wrong with. If I hit something and my tire's going flat, I'll feel it. I'm usually the guy that can hear or feel something way before any mechanic could even tell something was going wrong.
Again, some people see it as a convenience, I just see it as another electrical system that could give me trouble.
