I'm not working for LispWorks, but I use it since many years. LispWorks is a relatively expensive commercial implementation of Common Lisp. There might be several reasons to buy it: cross platform GUI support (Windows, Linux/Unix, Mac), integrated IDE, various delivery options for applications, support for various hardware / operating systems, ... I personally also find the runtime system quite robust.
