Korn is (I think) a variant of the original Bourne shell (sh) written by
David Korn. It does have some advantages over the original 'sh' shell, but
then so does the 'bash' shell that most Linux users use. But you're comparing
apples and oranges here. Konsole/xterm/etc are terminal emulators, not
shells. A shell runs 'inside' a Konsole or an xterm (other things can run
inside them too, but the shell is what interprets commands you type on the
command line.) So if you are in an xterm and type 'ls' at the prompt, it is
(usually) bash that takes that as a request to run the 'ls' command, not
xterm itself.
Korn shell was popular with some, and it probably still is. Most people who
want Korn on Linux are likely familiar with using other variants of Unix and
have gotten familiar with that shell and like it. But (as far as I know) the
korn shell is still non-GPL - that may have changed, of couirse, I haven't
payed much attention to it. Also, there is a variant of Korn called 'pdksh'
which is fairly widely available and runs on Linux. And there is another
variant with loads of extensions called the 'Z shell' (zsh) included on the
Mandrake CD.
