...and the benefit of this is what?  Please understand, I'm not 
objecting to change if it's for the better.  I do, however, distrust 
change for its own sake, such as what's going on with Gnome 3.

As an example of "change for the better," when I first started using X, 
it took me a little while to get used to having a desktop that was 
bigger than the screen with a viewport that I could pan to different 
parts of it, but after a little experimentation and practice, I grew to 
love it.  Then, it changed to multiple desktops; not really better, but 
certainly easier for newcomers to understand.

Much of what's "under the hood" in Linux and X has been there, 
essentially unchanged, for well over a decade.  In computer terms, 
that's several lifetimes.  It's stayed that way because it's worked and 
(AFAICT) didn't need changing.  The attitude has always been "if it 
ain't broke, don't fix it."  Now, it's changing and I have to wonder: 
was there something wrong with the old way, or is there something 
significantly better about the new?  If so, I'd like to know what it is, 
not because I'm resistant to change but because I'd like to learn.

Back when I did tech support for an ISP, I turned myself into a Windows 
Internals geek.  Now that I run Linux, I'm something of a Linux 
Internals geek.  I may not be able to follow the code any more, but I 
can at least familiarize myself with what programs are doing what and why.

Sorry for such a long post, but I felt it important to explain why I'm 
asking and what kind of answer I'm looking for.
