Because it's simply the most universally useful program ever written.

Have you discovered iswitchb-mode yet?  You won't look back.

Yup... that's Emacs for you.

(and power) of Emacs :-)

Keep going.  Your investment _will_ mature in the most pleasing way
imaginable.

I'm not surprised to hear that.  I only ever use a mouse for browsing,
so I run emacs22-nox in gnome-terminal.  The emacs22-nox executable file
is just 4.9 Mb and the contents of /usr/share/emacs and
/usr/share/emacs22 combined is just 75.4 Mb, so we're talking ~80 Mb all
in.  I wonder how that compares with Eclipse and friends?

No one seems to have said it so I will... on behalf of the list, thanks
for what sounds to me like the beginnings of a ringing endorsement of
Emacs-as-IDE
