..hence the term "flavors" of UNIX/Linux.

Some are better tasting than others.

Here's another way to put it that might help. If you're used to DOS and
Windows, and especially Windows-3.1 (a mere 6 years ago), the following
correspondences can be made:

kernel = msdos.sys
shell = command.com
gui = windows

Even under Windows9x, those elements are still there.

Under the typical Unix, the elements look like:

kernel = vmlinuz (Linux), genunix (Solaris), kernel (FreeBSD), etc.
shell = sh, csh, tcsh, bash, ksh (tcsh and bash are the most popular)
gui = X11R6 + window manager + optional desktop

As you can see, the Unix world gives you many more options than the
DOS/Windows world. Not only do you get to choose your shell and gui
elements, you can also customize your kernel. If you're a pessimist it
will sound like you get your choice of ropes to hang yourself with. If
you're an optimist it will be more like a candy store with something new
and tasty every minute.
