If you're still using a wall telephone with a cord and refusing to buy a cell phone, your more tech-savvy friends might accuse you of misoneism, or hating new things.
The noun misoneism is one way to describe a suspicion of innovation, or a stubborn tendency to stick with the older ways of doing things. A farmer's misoneism, for example, might lead her to use plow-pulling oxen rather than tractors and to milk her cows by hand rather than using newer milking machines. The Greek word for "hatred," misos merges here with neos, or "new."
