It certainly is! That's why I choose software that I think is beautiful.

I may think a terminal window is beautiful - if I do then I will choose a terminal.

What I won't do is purposefully use user-hostile/ugly software on principle - if there is a better choice I will choose the better choice.

Beauty is created by the conniving artist. It is 'absorbed' by the user. Not necessarily all beautiful things are useful.

Beautiful software, looks good, is intuitive, doesn't complain and complements the user. Hence software is different from art.
