Actually I tend to differ with that statement. Latest software is always more secure and less buggy. I would personally prefer having my workstations with all the latest software.
Older software is usually vetted and proven functional in the particular corporate environment where it's deployed, doesn't conflict with other software, etc. My friends in corporate world have told me how it takes X many months for upgrades to be rolled out because they must be tested in sandboxes first to make sure nothing explodes unexpectedly.
This apparently applies to all software, from OS updates down to individual program updates.
I am curious because your comments, and the way they are worded make it sound like you are not from the US and you are young.
