These days, a Common Lisp programmer is as likely to use a vector, a hash table, or a user-defined class or structure as to use a list.
Practically speaking, lists remain in the language because they're an excellent solution to certain problems. One such problem—how to represent code as data in order to support code-transforming and code-generating macros—is particular to Lisp, which may explain why other languages don't feel the lack of Lisp-style lists.
