Is it worth buying more Mathematica applications?

I am asking, because it seems these applications are hardly ever being 
updated.

Look at the structural mechanics application

http://documents.wolfram.com/applications/structural/index.html

It is still version 1, and the copyright shows it was published in 1999. 
This is 7 years ago !! This is like a million years ago in computer software 
time.

The control systems application
http://documents.wolfram.com/applications/control/FrontMatter/0.2.html

Still at version 2.2 since January 2003. This is 4 years ago without any 
single update.

The Signals and Systems application
http://www.wolfram.com/products/applications/signals/

Still at version 1.2.1 from 1995 (this is 11 years ago).

And I can go on and on.

Another big problem is that it is almost impossible to figure what version 
number these application are at and when was the last version released. It 
is as if this is intentionally kept hidden.  Look at the mechanical system 
package

http://www.wolfram.com/products/applications/mechsystems/

It says at the top "NEW VERSION". but no version number or when was this 
version released. When you scroll to the bottom of the page, it says 
mechanical system 2. Then it says 1994-2005.  Whatever this is supposed to 
mean is anyone's guess.

Can any one from the company explain all of this?

I was about to buy the structural mechanics package, but last minute when I 
checked the date on it, and that it was still version 1 since 1999, I closed 
the window and did not buy it. It is clear that there are many dead 
applications that are not being maintained and are still being sold to 
customers.
