The great question of the day has been solved, and it is Emacs that wins.
Not that I use Emacs, mind you, but I've said for years that sooner or later, GNU/Linux would go away and be replaced by your choice of KDE/Linux (KDE having taken over so much functionality that all it needs is a kernel) and Emacs/Linux (Emacs already being almost an OS, except for missing a text editor). The only question was which would happen first.
Well, looks like Emacs has now run that race. Probably not as grandma-friendly, though, as the alternative. (And no, I don't mean vi.)
