It's more about switching cost than taste. (And responding from identity). Getting a new girlfriend and getting a new text editor both require some effort. Your current one may not be perfect, but you know it pretty well. Is it worth the time investment to change? Maybe the new one will really be better, but maybe it'll just be different. Better in some ways and worse in others.

The analogy breaks down when I remember I know people that like to get a new girlfriend every few years. I don't know anyone that likes to switch editors every few years.
