If a technological advance befits the user, it is worth considering. If it doesn't benefit the user, why go there? I know a lot of people who still have a flip phone because it does everything that they need it to do. If a cast iron head does everything the owner wants, why spend money on something else?

One example I think of are the newer refrigerators that have the see through door. Really? Now we are too lazy to open the door? And paid a premium for not having to open the door.
