Wow, this is a momentous day for me. I've been a hard core xemacs user 
for the last 12 years. And I've finally decided to switch over to  
emacs. I'll miss the nicer look and more streamlined and clean cut 
interface of xemacs. But after the release of emacs 22 and things like 
column support and such in org-mode which is available only in emacs 
have convinced me that the tradeoffs in sticking with xemacs was just 
not worth it... Even other packages are always better supported in emacs 
.... Ah well, xemacs I'll miss some of your features ! but auf 
wiedersehen, it's time to say goodbye to you...
