Yes, that is what threw me. I understand Apple in under NO obligation to include Stuff Expander in the OS. BUT, and here is the clincher, because IT WAS included in previous iterations many installers made in the PRE 10.4 Tiger era are encoded in the SIT format. NEW users to the OS would have NO idea what to do when confronted with the "please choose an application to open this file" dialogue.

As I've already stated, Apple has no obligation to include Stuffit Expander, but in the interests of a "smart" user friendly OS, there should be some prompt about what file type this is and give a point in the right direction. OR like the MS win system have an option to open a web page listing filetypes and their controlling apps. NO I'm not a troll, or pro win. But heck, Apple can do better than this.
