I certainly like instant coffee and prefer it over many other types I have tried. It took a few tries to find a good one, however. Perhaps it's because I mostly like coffee quite milky, which might cover over any quality issues.

Developing a taste for good coffee (or wine, etc) doesn't seem attractive to me. You end up needing more and more equipment. You need expensive high quality beans. It's typically messy, time consuming, takes up valuable kitchen space and expensive. I'd rather something ok, which is quick, cheap and convenient.
